how to fix it

[NemoPS]

check that a file named Tools.php is in the classes/ folder. If not, grab a clean zip file and extract, then upload it to the server.

Is this an error with php 7.2.22?

[prestol]

updated to 1.7.6.1 and it works again..

For any one who facing this issue, just delete or rename the DEV & PROD folders in /var/cache/  error will gone, its a cache issue more likely with multi stores

 

Thanks

which prestashop version do you have? the "Var" folder is always there at root in public_html

the var folder is not in public_html, not in debian or ubuntu

Where is the Admin folder? "Which prestashop version do you have"

[Nickz]

in the install folder called /tb path is home/admin/web/xxxx.com/public_html/tb

Latest version.

var/cache is under the root folder of the server. Same level etc is on.

So delete this cache folder - Also the Var folder will be in home/admin/web/xxxx.com/public_html/Var  if its not there  that will mean that you have permission issues, that is why the VAR folder is not creating automatically

I slowly come to think that you lack insight about linux servers.

And what is inside TB folder? please note that the files does not differentiated in linux or any other servers, they remain the same in a folder.

The solution was to grant permission to www-data in cache, themes, mails, install and config.

As I said there are no var folders inside public_html

They will be in your shops folder - public_html/*your_shop*/var/cache is generated/regenerated automatically, Prestashop won't work without

Sorry to refloat this thread, but I have a similar error and cannot fix it in any way. I have already deleted the contents of the var / cache folders, but there is no way.

I´ve already deleted the var/cache content, but it doesn´t work. 

I cannot acces to the backoffice, we obtain a 500 error. Is something intermittent. sometimes it´s work correctly.

What have you done to cause that.

It won't happen out of nothing. Except if your server outphased a php version the shop need to work smoothly.

[eresturamoncin]

I don't know what caused it. It is difficult to know from when it fails, as I already said that it is intermittent. The front works correctly. But it's quite annoying having to reload the backoffice page while serving customers. I have also tried to deactivate the few modules that I have not native to prestashop, but it does not work.

Thank you for your time.

Please turn on Debug mode and post the error.

Seems PHP 7.3 is not compatible with one of your module, also try to downgrade the PHP version and check.

Best regards

I just upgrade PHP version to 7.4 and the error keeps happening. The debug does not provide any type of additional information because the 500 error is before the debug starts to act. I'm desperate now. I do not know what else to do. I have disabled the modules that are not native to prestashop and the same thing keeps happening.
