Error 500 / Compile Error: Multiple access type modifiers are not allowed

[skyppye]

Hi all,

My website under Prestashop 1.7.6.3. has been runnijng smoothly for over a year.

Today, I decided to switch from a module that would import products automatically to manual product handling.

I deactivated the module and then cleared cache. Now I get: 

(1/1) FatalErrorException
Compile Error: Multiple access type modifiers are not allowed - in Product.php line 4

Backoffice is running as long as I'm not going into products menu or into shop parameters. Front office is not running at all.

Any ideas?? Attaching error screenshots.

Thanks!

Deactivte the override by renming it's file - it look corrupted, can be a leftover from the module
