I am using Zen Cart version 1.3.8a.
I have just moved my site from NoMonthlyFees to Bluehost.
I have only the local sales tax add on installed
I have only customized the stylesheets, and turned the layout boexes on/off.
I have searched the forum/FAQ.

THe problem started when I moved the site from one host to another. I followed the instructions in the FAQ, and it seemed to go smoothly. My store and admin area are functional, with the exception of the LinkPoint payment module. I configured it before moving the store , and it remained configured after the move (e.g the store # stayed in the module, and it remained as 'Testing Successful'). I wanted to try the 'testing declined' but when I go to admin->modules->payment, then to LinkPoint, I can edit it, change to Testing declined, and save it. No errors are produced, but when I go back, it remains on Testing successful. I have tried to change it to Liveroduction, but that doesn't work either. I have tried enabling/disabling/ editing other modules, they seem to be fine. I can add/delete products from my database, so that appears ok too.
Any ideas?

Thanks in advance!
