Magento white screen after disabling Mage Module output in Advanced Configuration - magento

I'm developing a Magento store and there is a guy that manages the store, we were transferring the store to another domain but the old one was with all products.
The guy went in advanced configurations and disabled all modules in the old Magento installation, even the Mage ones and now the initial page is white and the admin is too, what could I do to solve this problem?
The version of Magento is 1.9.1.1.

So, he disabled all the Mage modules, including REMOVE ENGINE ie Mage Core?
Hmm...
Ok, here's what you do.
Use phpMyAdmin to open core_config_data, sort table by path and look for all the paths beginning with advanced/modules_disable_output/Mage_ and change the value from 1 to 0
Then delete all the mage--? subfolders in var/cache/ so Magento is forced to reload the configuration data out of the core_config_data table.
This should put your engine back in so the old jalopy will run.

How can I manually remove a joomla 2.5 extension?

I accidentally installed a more recent component of J2XML designed for Joomla 3 into my J2.5 site... and now I have no idea how to remove it. The only Admin page that works is the main Admin page... all the other admin pages are blank... I'm assuming it's logging the error somewhere, but I have no idea where that would be.
Can I manually remove the extension/module? What database tables should i remove?
I have already removed the folder of files, but I'm not familiar enough with the Joomla db structure to know what damage has been caused.
And in this case, backups have failed me.
you should able to look at _components table and remove J2XML entry so it doesn't show in administrator panel

Is there a way to re-install the default Magento theme?

I inherited a Magento store from another developer who tried to customize the default theme and made a mess of things. I'd like to install a fresh template but need the default theme back in its' original form (without the customizations/modifications made by the previous guy). There are no backups available for me to roll back to.
Is there any way I can download and re-install the original, unaltered Magento default theme, or do I need to start with a fresh installation of Magento to obtain this?
There is no solution that I know that comes out of the box regarding templates rollback (as there is not for rolling back sql table schemas...).
You can get the version of the Magento via Mage::getVersion() and it should also be displayed in the footer of the admin panel.
From there, you can download any version of Magento from Magento's website and overwrite the whole directory app/design/frontend/default/default and/or app/design/frontend/default/base depending on the version.
You don't have to get the whole Magento to a fresh install... But chances are, that if the template is that a mess, you could also have to deal with core files modification (the worst) and may want to actually start from a fresh Magento install.

Magento Admin Backend Blank Page after disabling Mage_ extension accidentally

I was disabling the extensions one by one to check a problem, but accidentally disabled some of the core extensions. Immediately the backend went blank and so I tried to enable all the extensions that I disabled in etc/modules. After that I cleared everything inside var folder but it was still not working.
So I copied the whole of etc/modules folder to replace but it still doesn't work after clearing cache by deleting cache folder.
Then I copied app folder and change local.xml, but it still doesn't work.
How can I restore back my admin page?
My Magento Version is 1.7
Thanks.
Since you have disabled the modules from backend you need to enable it directly from database.The table core_config_data holds the data whether the module is enabled/disabled.Execute the below query and it will list all the available modules
SELECT * FROM `core_config_data` WHERE `path` LIKE '%advanced/modules_disable_output/%'
Now choose the appropriate row and set the value to 0.

Magento cart page is not showing

My Magento cart page is not showing at all. It just comes up with a blank page. Previously this site was developed by another developer and He has disabled the Checkout process. Now I cannot find which settings he has done to stop the checkout process.
Can anyone tell me what are the possibilities to stop the default module from working.
Also every thing else is coming right on the cart page. Header and footer and all the things just that it is not rendering the html for cart block. The Content just came up empty, with no HTML.
Please open the adminpanel and then go to the
System/Configuration/Advanced
there is a tab Disable Modules Output and then enable the Mage_checkout module
As I have told you the previous developer have disabled the modules. But that was not the case the developer have installed some extensions to disable the checkout process but that does not work very well. Then he tries to delete the extensions the wrong way so the entries that were made by those extensions was still in the database table "core_config_data".
And these values are being used by the left over files of the extensions ans he has overridden the magento core files for that. I just copy and replace the core magento files and also cleared the table "core_config_data" table and all things got working once again.

opencart theme not changing

I installed opencart 1.5.6 on my localhost, and it's not possible for me to change the theme. The admin panel says the new theme is active, but the default theme always appears.
I made the same installation on a remote server, and everything is working well there.
I have no idea what's wrong on my localhost. I'm on a new installation on Ubuntu 12.4 with a default configuration for LAMP. I tried to compare the two phpinfo but there are so many things that are different that gives me no clue.
It was just a problem of rights on the theme folder. Very stupid ...
First, I would check your database to see if the change is registered. Use phpMyAdmin (or whatever included with your LAMP stack) and look at the "oc_setting" (prefix may differ) and see if the config_template is set to the template you've chosen via the admin. This will help identify if the issue is database related.
I have the solution, the ACTUAL solution. (For me anyway)
Extract the theme.
Login to your OpenCart website using FTP. Please read our article if
you need help using FTP.
Upload the catalog and images folders to the root of your OpenCart installation.
Once the upload is finished, log into your OpenCart Dashboard and go
to System > Settings
Choose your website from the list, check the box next to it, and select “Edit”
In the store tab you will now see your new theme option available under 'Template'
Click Save.
It has now been updated.
Many, many tutorials online at the moment incorrectly instruct people to upload their theme directly into the catalog > view > theme location as though it were a WordPress theme or similar. You actually need to put the appropriate resources where they need to be.
