I was trying to upgrade with command line from 3.1.2 to 3.3.5

i’m using an 02switch hosting (mutualised) for my website.

My mautic is in a subdirectory and everything was fine since today :

Here is the folder organization:  
/mautic  
/wordpress  
Symlinc in /wordress/marketing → …/mautic  
and i’m accessing mautic using web address with [domain-name.com/marketing/s/login](http://domain-name.com/marketing/s/login)

Before upgrading, everything was fine, but right now I can’t find what’s wrong, i’m redirected to the wordpress router who finaly display a 404 (it’s logic that it can’t found anything)

i’ve properly changed those value in app/config/local.php  
“site\_url”  
and all path for the storage

Can you help me please ?

PS: it’s only a “transition” cause i’ll next upgrade to mautic 4, but i tried upgrading directly to mautic 4 and i had the same issue

I also tried to disable mod\_security but this doesn’t fix my problem

best regards
