every Time I install new mods I am getting error
 

A conflict was detected in the bitfields. You cannot continue with the installation of this product until this has been fixed. The conflicts found were:

Bitfield Collision: credits_cantearn = allowvideos
Bitfield Collision: credits_cantshow = bypassdp
Bitfield Collision: credits_cantaward = displaywrt
Bitfield Collision: credits_modawards = canreputation

Possibly a conflict with whatever mod that has that? If you don't know what could be conflicting, I would try systematically, disabling mods through the Product Manager, one by one. As you disable one, try installing new mods. Keep going until your able to find your conflict and are able to install mods, or you have disabled the last one and your still getting the error.

Thats my advice. :)

If you're no longer using the vb credits mod, remove the bitfield files from your server via ftp.

Yes. Which is why it's very important to always remove every trace of a mod, once its not being used. :)

Thank you so much for the tips .

Can you tell me where is located bitfield files ?
and can you please tell me which file i need to delete .

Check the /includes/xml folder for anything named _credits or _vbcredits

Thank you now I can install mods.
