no backend access

Hi, I'm a bit worried because yesterday I installed the storefront quickstart for J3 (adding languages: catalan and spanish) and I made all the changes I wanted. Everything worked fine.

Today I went to the front-end, it's offline and with my admin details (user+password) I can see the website, still not finished. Then I tried to access to the backend but it was impossible. When I typed www.XXX.org/administrator it redirects me to the frontend.

I checked the error_log (I can access via ftp) and I see a lot of error depending from Virtuemart and NewsPro gk5....
I am desperate because the website had to be ready for tomorrow, today I only had to change some details and publish it but I can't access to the administrator panel

The last errors:

I can give the access in a PM, I need help, really.
Thanks.

Hi

Those messages are only notices, not errors, so there is nothing to worry about that. Bigger problem is that You cannot login to administrator panel. Is it possible that someone has hacked into it and made changes to the site ?

Yes, you're right, the technical support of my server solved the problem, someone changed the .htaccess....
Thanks for your reply.
Regards

Hi

Great to hear it's solved now. Ok. Thread closed than.
