vBulletin 4 Not Installed: Server Error

Hey guys, I am having a few issues verifying the tapatalk install on my forum.

I did a test forum install (as I am migrating from phpBB), and the test worked fine on a separate server (xxxxx).

Now I have moved the 'real' forum over, installed tapatalk, and tried to verify. I now get the "Not Installed: Server Error" message when trying to verify. The new forum is xxxx. I have tried to CHMOD the mobiquo directory & contents to 755, and the usual steps you suggest.

Any help is appreciated.

Thanks.

Apologies...

xxxxxx

Yao,

Thank you for that, it works great. I did see that tip, and did make the edit; however I missed the change on the first line.

Thanks again.
