ClassNotFoundException - PrestaShop 1.7.4.3 - prestashop-1.7

Hello I have a problem with PrestaShop 1.7.4.3. After trying to log in to the Admin panel, errors appear as in the attached picture.

I will be you, either I would reinstall my Prestashop, or I would install it somewhere else and I would put all the Vendor folder that is at the root to correct the problem.

There has been an error processing the request magento

My magento sito got crashed after installing an old extension.. Actually the site turned into maintenance mode after this installation. So I removed maintenance.flag file from root folder. But that did n't solve out the bug. Now we are getting "There has been an error processing your request"
How to solve this? Thanks in advance
You have to navigate to magento /var/report/
and find this report number, read this file contents

After uploading images in the magento product is unable to show

i encountered a really weird problem in my website. If i am adding a product with images then it failed to load my website completely and also the product is not showing properly. My images and media directory permission are 755.Any solution for this?
Try to rename .htaccess file within magento/media/ folder and check once again.
Hope it would help.

WYSIWYG magento issue in admin

I have a problem with one magento installation version 1.7.0.2
when I try to upload an image through the WYSIWYG editor in the cms pages for example when I click on browse server I get this error:
error: error in [unknown object].fireEvent():
event name: open_browser_callback
error message: Dialog is not defined
SO far I haven't found the same error so if anyone can help out I'd be very grateful.
Also in product WYSIWYG editor it doesn't load and says
Window is not defined.
I guess the error is the same.
Thanks!
I had the same problem on 1.6. Fixed it by overwriting the complete js folder
I had the same problem on 1.7.0
I go to the Magento "old versions" repository and downloaded the whole CMS
Then I replaced the whole existing js folder in that the fresh installation...it works :)

Magento Connect not working (shows magento installation)

There is a strage problem in my website's magento connect feature. Whenever I will click on Magento Connect, it will show me the installation page of magento.
The url is something like this
http://www.mystore.com/downloader/?return=http%3A%2F%2Fwww.saletab.com%2Findex.php%2Fadmin_panel%2F
Is this because someone changed core file? Or because I am ruining magento 1.7 and 1.8 is released?
Please note that another instance, of the EXACT same code and database works fine when I click on magento connect, but not this one.
Please tell me how to resolve this problem?
first you need to check your file directory , there is 1 folder " downloader " if this folder is rename then please set name that i mention in quote , and if not available then please download fresh magento and copy that folder to in your file directory.

Problems uninstalling SEO Boss extension in Joomla 2.5

I have created a website named www.connectedipvoice.com and installed SEO Boss extension. Somehow it was not working so I tried to remove it using my administrator mode from my website but it shows a message:
JFolder: :delete: Path is not a folder. Path: /home/content/54/9492054/html/components/com_seoboss
Component Uninstall: Can't uninstall. Please remove manually
Then I tried to uninstall directly from server but it's not showing there too. My problem is when I try to install it again - it's showing me that the file is already installed and when I checked in the extension area >
manage catagory I found that SEO Boss extension is still there. But now I'm unable to get the options to remove it - the status column becomes blank!
To properly uninstall it (so you can install it again) you need to also remove the component reference inside the table called #__extensions
Search the element field for anything containing "com_seoboss" and delete it.
Then you should be able to install it again.
You should also look for this and delete it - /home/content/54/9492054/html/administrator/components/com_seoboss
I am not too sure what you mean by 'i tried to uninstall directly from the server'.
Anyway, I have had a similar issue to you when I was trying to uninstall virtuemart from a website. What worked for me was to:
manually delete all the component folders (using an FTP client like Filezilla )
manually delete all component tables from the database (using phpMyAdmin)
If you try this solution, make sure you backup your database first.
Hope this helps.
