vBSEO 3.6
vBulletin 3.6.8
vBET 2.3.x
vBSEO sitemap

I installed the free version for a test and I have found out the translation works great!

However, there is a major issue on URLs:

My site is a social networking site (URL xxx.com) integrated with a vBulletin v3.6.8 forum (URL xxx.com/forums).

After installing vBET and made changes to forum root .htaccess, I encountered a problem - once I choose a translation, I cannot go back to xxx.com as all the xxx.com URLs now becomes xxx.com/forums.

For example URL xxx.com/index.php?page=music now becomes xxx.com/forums/index.php?page=music and therefore the social networking part of the site is completely broken as all URLs are redirected to vBulletin forums.

And, the forum URL, which was xxx.com/forums, not becomes xxx.com/forums/forums.

If I turned off URL tracking, above problem would be gone but the automatic translation also stops, which is not what I want.

I put /forums as Forum directory parameter in vBET settings, and I followed the instruction to change .htaccess for vBSEO users.

What am I missing?
