1.6.1.12 | Blank page after saving/editing product pages

[YanK1973]

Hello everyone,

out of the blue i have the following issue:

after editing a product (changing price or quantity for example), the price or quantity changes but i am redirected to a blank page. I can see that changes are applied when clicking back on browser.

- No new installations, updates or any changes or actions from my side.

- Turned defines error reporting on, no messages at all.

- I cleaned Cache form Performance tab.

- I tried Disabled Overrides .

- I tried Force compilation of Smarty.

- I tried various browsers, devices etc in order to exclude a local cache problem.

- Browser console not very helpful or at least not for me.

- Finally, i checked php error log and it displays this pair of errors after every click on save:

[22-Feb-2022 15:57:43 XXXXXXXX PHP Notice:  Undefined index: jq in /home/XXXXXX/public_html/cache/smarty/compile/a9/18/31/a918317463049be5f2a21fa8c3331bcfc96607ff.file.header.tpl.php on line 28

[22-Feb-2022 15:57:43 XXXXXXXX] PHP Notice:  Trying to get property of non-object in /home/XXXXXXX/public_html/cache/smarty/compile/a9/18/31/a918317463049be5f2a21fa8c3331bcfc96607ff.file.header.tpl.php on line 28

 

The line mentioned above are empty (see image).

 

Prestashop v. 1.6.1.12 and PHP v. 7.0

 

Any help is appreciated

I changed PHP version to 5.6 and problem is resolved.

Don't really know if it is a solution or if the best method to solve an issue is to downgrade PHP, that may screw something else up, hoping for the best
