Fatal error: Class 'ToolsCore' not found in public_html/classes/PrestaShopAutoload.php(114) : eval()'d code on line 1

[ej.farsta]

Hi,
suddenly I'm having a fatal error and I cant access not front office nor back office. After turning on debug mode via ftp I'm having this:
Fatal error: Class 'ToolsCore' not found in public_html/classes/PrestaShopAutoload.php(114) : eval()'d code on line 1

I changed the file with the new one from repository however without any effect. Could you help tell me what can be wrong and how to repair it? Presta 1.6, no changes were made to the website for months and months so I have no idea what happened...
Back-up from seven days before - same situation 😕

Hi,

Delete the cache files from the '/cache' directory and check.

[ej.farsta]

All folders and files? Leave only an empty "cache" folder?

Delete all the files and folders inside the 'cache' folder. Do not delete the 'cache' folder itself.

[ej.farsta]

Didn't work...

[wepresta]

Just delete or rename the DEV & PROD folders in /var/cache/  error will gone, its a cache issue more likely with multi stores

[ej.farsta]

I don't have a var folder

[wepresta]

Wich PS version pls ?

[ej.farsta]

1.6. Cleared all cache folder and blank page is still there.. no acces to BO as well.

[wepresta]

Did you check if PrestaShopAutoload.php is correctly in the classes folder ?

[ej.farsta]

The file is there, however I don't know if it is "correctly"...

 

 

[wepresta]

Could you attach here PrestaShopAutoload.php please ? I will check

Have you maybe found a time to look?

[wepresta]

Try to change :

Tools::error_log('Cannot write temporary file '.$filename_tmp);

to 

\Tools::error_log('Cannot write temporary file '.$filename_tmp);

[ej.farsta]

Unfortunatelly didn't work

[AddWeb Solution]

Hi,

Let me know the php version you use.

[ej.farsta]

7.0, I tried 7.2 but didn't change anything

[ej.farsta]

Thanks to @wepresta the issue has been solved. How? I have no idea but in case you have any issues - hit him and he will help you!
Thank you again

[Isaid Cornejo]

I have the same error and I cannot resolve it @wepresta. Can you help me?
