Cant install extension on Joomla 3.1 - joomla

I am running joomla on IIS 7.5 and MSSQL, everything seems to be working just fine, but when I install JCE Eqitor from the admin panel it times out and when i check the logs for error this is what i got:
PHP Notice: Undefined index: cache_entries in
D:\Joomlawebsite\libraries\joomla\cache\storage\wincache.php on line
147
PHP Warning: Invalid argument supplied for foreach() in
D:\Joomlawebsite\libraries\joomla\cache\storage\wincache.php on line
150
I have IUSR permission as well.

Try to completely uninstall extension

also modules and plugins if extension have.
Try to clear your site cache.
Go to global configration and check your site all folder's has writable permission.
try to install again with jce installation doc. http://www.joomlacontenteditor.net/support/installation/editor/item/install-or-update-the-jce-editor-in-joomla3

Prestashop 1.7.7.5 installation issue : ps_facebook1

On Centos8, issue during installation of Prestashop 1.7.7.5 (also with 1.7.7.4) :
Installation issue
An error occurred during installation...
ps_facebook1: Cannot install module "ps_facebook"
Tried lot of things but nothing works...
I can suggest a temporary workaround:
After you get the error delete content of ps_facebook module folder
(delete the content, not the folder!)
Change folder permission to 400
Try installing again

linking firebase firestore with laravel

I want to test Firestore with laravel. But before i can use it, I need a couple of tools.
I'm stuck on gRPC. I installed it, it's working on my windows and I can install Firestore with Composer, but I can't get it to work with XAMPP. When I load a page I get:
Fatal error: Uncaught Google\Cloud\Core\Exception\GoogleException: The requested client requires the gRPC extension. Please see https://cloud.google.com/php/grpc for installation instructions. in /vendor/google/cloud-core/src/ClientTrait.php:75 Stack trace: #0 /vendor/google/cloud-firestore/src/FirestoreClient.php(115): Google\Cloud\Firestore\FirestoreClient->requireGrpc() #1 /app/firebase.php(18): Google\Cloud\Firestore\FirestoreClient->__construct() #2 /app/firebase.php(21): App\initialize() #3 /template.php(688): require_once('/Applications/X...') #4 /template.php(647): load_template('/Applications/X...', true) #5 /App in
/vendor/google/cloud-core/src/ClientTrait.php on line 75
It may be the case that the gRPC extention is not enabled on the php.ini file, you can enable it by:
On PHP version 7.2 and up: add extension=grpc on the php.ini file
On older PHP versions: add extension=php_grpc.dll on the php.ini file
And then restart XAMPP and the extension will be activated as showed in phpinfo() and it should work.
If this does not work, a workaround for the issue is to download the gRPC DLL and add it to your project's extentions manually. You can download the latest version on the PECL repository for gRPC (Choose a stable version), and extract the php_grpc.dll file to the extensions folder in XAMPP, which the path you can find on the php.ini.
After that, enable the extetion as described earlier and restart XAMPP again.
Let me know if this fixed your issue.

Cloudstack client installation

I have XAMPP installed on Windows 10. And have successfully installed Composer, Laravel. I can see the basic Laravel project page on my local server.
Just to try things out I also installed yii2. I can see the basic yii2 page also on my local server.
Now I'm trying to install this Generic Cloudstack Client:
https://github.com/PCextreme/cloudstack-client
In XAMPP, under htdocs I have this dir called 'LaravelProjects'.
dir structure
First I made the project with the laravel command:
laravel new PCextreme
Then in PCextreme directory I give the command:
composer require pcextreme/cloudstack-client:~0.1
The composer breaks and shows Conclusion: remove laravel/framework 5.2.41
But in the instructions there is another method to install the package.
When I do that by editting the composer.json in the main Laravel dir. 'LaravelProjects' under xampp/htdocs with these lines:
"require": { "pcextreme/cloudstack-client": "~0.1" }
And then I run the "composer update" command.
I don't get any error.
But as soon as I follow these steps:
Once the package is installed you need to open app/config/app.php and register the required service provider:
`'providers' => [
'PCextreme\CloudstackClient\Providers\LaravelServiceProvider']`
The application breaks.
I can't see the basic page showing 'Laravel 5' on my server anymore.
Instead of that I get a fatal error:
Whoops, looks like something went wrong.
1/1 FatalErrorException in ProviderRepository.php line 146: Class
'PCextreme\CloudstackClient\Providers\LaravelServiceProvider' not found
Further in the instructions, when I give the command below:
php artisan config:publish pcextreme/cloudstack-client
I get this error:
[Symfony\Component\Debug\Exception\FatalErrorException]
Class 'PCextreme\CloudstackClient\Providers\LaravelServiceProvider' not found
I have tried out different things that I could find on internet but nothing seems to work in my case.
Could someone kindly help me out with this? Any help is greatly appreciated!
Execute in you project folder command: composer update

Joomla: Blank site when uninstall a component

I have installed AdvancedModuleManager while trying to assign modules to certain pages. However It did not work as I wanted and when I tried to uninstall it from the Administration panel - the website gone blank.
Both /administrator/ and front end are blank.
Any ideas how to fix it?
[22-Apr-2016 21:25:36 Europe/Sofia] PHP Fatal error: require_once() [<a href='function.require'>function.require</a>]: Failed opening required '/home/public_html/libraries/regularlabs/helpers/functions.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/public_html/plugins/system/sourcerer/sourcerer.php on line 41
The problem was that I have installed another Plugin called "Sourcerer".
Both "Sourcerer" and "Advanced module Manager" are made from "Regular Labs" and when I uninstalled the AMM I also uninstalled their common component called Regular Labs Library...
Installed it again and everything was fine

Magento 1.9.2.1 (after upgrade): Fatal error by saving product

I did upgrade on my Magento shop from 1.8.1 to 1.9.2.1 - almost everything worked well. Only saving products ends with a fatal error:
Fatal error: Call to undefined method Mage_Sales_Model_Resource_Quote::markQuotesRecollectByAffectedProduct() in /usr/share/nginx/www/magento/app/code/core/Mage/Sales/Model/Observer.php on line 135
The function is definitely there under /app/code/core/Mage/Sales/Model/Resource/Quote.php
On the server is nginx 1.4.6 with PHP 5.5.9 and MySQL 5.5.44
/var/cache/* and /var/session/* was cleared
cache is also disabled
I did also reindex
any ideas?
Thanks in advance!

For those who might have this problem again:
Magento uses an override of core files in local folder, and also in
community. So have a look at these folders also even if you called a
Mage class.
