Http 500 internal server error

[Warrick11]

Hi Forum people,

 

I had a technical issue come up last night with my prestashop.

 

Located: www.beeware.co.za/shop2

 

I was working in the back office and then wanted to see the front end and when I clicked on the "View my shop" link and now the shop front is not available and neither is the admin panel.

 

The only thing that happens is the error appears with message:

 

http 500 (internal server error)

 

Apparently, hosting company says there was a security breach [hack] on the server side.

 

Option 1)

My BIGGEST question now is how can I "reinstall" prestashop and link it to the old Database - assuming the database is still intact? Is that possible and could you give me steps to make sure the prestashop install links to old database?

 

Option 2)

Can I just replace the index.php or some other files on FTP server to FIX issue?

 

 

 

 

Urgent assistance please.

You may reinstall it by uploading all files to your server (via FTP). But if you wish only to change database your installation is using now, edit he file /config/settings.inc.php on your server.

What a relief!

 

Looks like the site is restored from host side.

 

Woohoo.

 

Prestashop LIVES!

Next time you see a 500 error in Prestashop, try first to enable error reporting as described in my signature, it might be worth fixing a small bug instead of reuploading everything If it can be done, of course!

Maybe it will be useful information for some of you:

 

I had problems with HTTP Error 500... and spend many hours reading forum topics and trying many solutions... turning on error reporting / disabling some modules / reuploding files / cheking server configuration and many more...

 

Finaly I found solution in some blog, away from PS community Its:

1. Turn Off and turn On the SEO friendly URLs. This will generate the a .htaccess file on your root.
2. Download the .htaccess file. Comment the line “SetEnv HTTP_MOD_REWRITE On” by putting # before the line and reuplod.
3. If the version of PHP running on your server is 5.4 (5.5 / 5.6), change it to 5.2.

 

This should solve your problem
