Forbiden to access /administrator/index.php

[erbi]

Hello everybody!
I have a big problem, because I like to change vendor data. If changing anything or nothibg (only click cancel) VM display white page with:

Forbidden

You don't have permission to access /administrator/index.php on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

What is this and how resolved? Joomla 2.5.16. VM 2.0.22c

HI,
Almost 100% the problem is with site hosting.
Try to create custom html module and see if You get the same error.

[erbi]

Custom modul create without problem

I don't know is this hoster problem.
If create subdomain and install fresh VM work, but if in this subdomain copy backup of main domain, not work

Have You enabled cashe on site?
1)try Site-> Maintance -> Clear Cache for all.
2) write absolute path for tmp and log folders in joomla configuration

[erbi]

Yes: enable cache, clear cache, absolute path for tmp and log is /home/resti/public_html/mywebsite.com/logs, home/resti/public_html/mywebsite.com/tmp. With installing any extensions are no problems.

Hi,
I has such a problem with vm2.0.10 . The problem was with my hosting. But in Your case I don't know.
Also I  do not suggest You to use cache with VM.

Problem solved.
Hoster say:

Maybe is this virtuemart bug, because vm requires too many simultaneous sql connections ...

Now work, because hoster correct server settings.
