Every time I try to add a mod
 

Each time I try to upload a new product to my site I get this 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: prefixrequired = credits_cantearn

I don't get what to do about it. PLEASE HELP ME!

you have vbcredits installed i think, uninstall it.

or you have installed it earlier and haven't removed its .xml files.

It's not in the uninstall menu so it might be the xml files I don't know.

That's the error you usually get when you havn't upgraded vBCredits after a forum upgrade. Are you sure you fully removed all the files?

No... but I don't think I installed it. Does this work with vB experience too? What are all the files??

There's no way you'd get that error if you didn't at least once try to install vBCredits. Download vBCredits in it's respective thread and look at the files in the download to make comparisons.

You need to remove the bitfield_xxxx.xml file associated with the "credits" modification from the includes/xml directory.

Already removed all of the files and it works now. Thanks, guys! :D

If you are using an old version of vB credits and this happens, you need to actually use the latest version, which changes the bitfield for credits_cantearn and allows many other mods to be installed properly. If you still want to use the old version, you can edit said bitfield file setting for credits_cantearn. Just for future reference.
