Error 404 Page not found, after trying to update from PrestaShop 1.7.8.8 to 1.7.8.9 using 1-Click Upgrade module

[ccristian]

Hi!

As I wrote in the title I am having an issues (Error 404 - Page not found) when I try to update the store from PrestaShop 1.7.8.8. to 1.7.8.9, using 1-Click upgrade module. The error occurs when I put the store into maintenance mode and trying to acces the 1-Click upgrade module.

 

Here are the steps I made:

1. I put the store into Maintenance mode;

2. Trying to access the 1-Click update module and BOOM... the 404 error occurs... and it get me out from back office dashboard into the front office of the store;

3. If I disable the Maintenance mode (set to off) It let me access the 1-Click update module again, but since the (1-Click update module) is asking me to put the store into Maintenance mode, the button to perform the action (upgrade) it doesn't appear.

 

Configuration:

PrestaShop 1.7.8.8,

PHP 7.4

Theme used: Warehouse (4.5.8)

Please help me to solve this problem, thank you!

Errors occurred after I activate the debug mode:
