[SOLVED] htaccess generates Error 500

[idefixxed]

Hello.

I'm getting Error 500 when updating Performance or SEO/URL. Well, just because of one extra rule @ .htaccess:

SetEnv HTTP_MOD_REWRITE On

(SEO/URL settings is not saved at all, Performance setting is saved well.)
 

Possible start of this problem could be at a migration of PS (ver. 1.5.6.0) from webserver with PHP ver. 5.4 (file system PS_DIRECTORY /../../) to another with PHP ver. 5.3.27 (normal file system). Both are virtual servers.

 

Fresh PS installation on webserver with PHP 5.3.27 works perfectly... Because PS doesn't put extra rule @ .htaccess.

 

Hopefuly, I've described my first "big" problem clearly enough.

 

Thanks in advance for any help or links.

 

Cheers

it would 'seem' that mod_rewrite is not installed on your server...

 

one should encapsulate any directives with check for module, in your case it would be

<IfModule mod_rewrite.c>

rewrite directives go here

</IfModule>

Thanks for your reply.
 
Here is a complete .htaccess file:

#If rewrite mod isn't enabled
ErrorDocument 404 /index.php?controller=404

Then I have to comment/delete mentioned directive:
 

SetEnv HTTP_MOD_REWRITE On

And yes, PS shows warning about non function mod_rewite module on webserver. Well, it is on... So, I'm going to contact my host tech support.
 
Cheers.

It would seem that mod_env is not installed.  It is required 'I think' for php running fast cgi.

[kmorgen]

As far as I understand the SetNev is no longer supported in PHP 5.4, and as Prestashop 1.5.6.0 keep adding this to the .htaccess, you will get internal 500 Server Error.

 

I have the same problem, since our host updated to PHP 5.4. How can we avoid, PS keep adding this?

Thank you very much for your advice!

 

Now PS 1.5.6.0 works perfectly.

 

Here is a note for Český hosting customers (http://www.cesky-hosting.cz/). Ask tech support for an activation of the "mod_env" module.
