Any clues as to try solve this ? ty

You should open those cache files and look at the content at the mentioned line number. And then you should find the same line in the original template file and look what goes wrong.

[El Patron]

enabel ps debug mode from performance page

recreate blank/500 page to get underlying php error

[rnervi]

cannot enable modes as admin page does not open

[ecommerce16]

you can do that by ftp or cpanel/directadmin

1. Connect to server via FTP or via hosting cpanel. Open your PrestaShop installation directory, navigate to config directory and open defines.inc.phpfile.
2. Find the following code (line 29 approximately): define( '_PS_MODE_DEV_' , false);
3. Edit the code: define( '_PS_MODE_DEV_' , true);
4. Save the changes and refresh the site.

Hi! I have exact problem, which of the backup modules you used, could you please share with me? Thanks

[rnervi]

Backup & restore

is payment one, cannot share !

I can send the restore php file.

analyze it and 99% you find what it does

restore - Copia.php
