1.7.8.8 - HTTP 500 Error signing into Admin Panel, after changing SQL database password

[sampsonzak]

So, I ran into a bug today, as I need to give a developer FTP access to one of my cloned / testing servers, I want to change the SQL password.

 

I went ahead and changed the MySQL user password, then updated it in the parameters.php file, uploaded. Front-end is working fine, as normal. Connecting and working.

 

But the back-end login, results in HTTP 500 Error, unable to log in. Not able to do anything.

 

Anyone have any idea why this is happening? If I change the password back to the original, it works straight away?? Really confused as the front-end is working with no problems.

 

Thank you

Have you tried to completely clear your browser cache to see if the front end really is working as it should? Try from your phone maybe.

I did refresh the cache. I changed the SQL password - checked the front end - 500 internal server error (expected), updated the parameters.php with the new password - re-checked the front end - front end is working, back-end on the other hand, not working at all. Doesn't show up the "500 internal server error" prestashop error template, but rather a 500 HTTPS error Chrome page.

 

Tried in incognito too, same result. 

 

Changed SQL DB password, and updated in parameters.php (password only). No idea why this would happen?

What happens if you create a new db user with new pw and then edit the parameters file?

So, I found another person with the same issue. This was resolved by deleting a cache folder:

 

Try to delete those cache's directories "dev" and "prod" .

Those directories are located here : var/cache/dev and var/cache/prod

 

 

Very weird but it's now fixed the issue.
