I followed the integration instructions for merging phpBB and CPG. It worked 100%. Then I went and played with the themes for both sites and now I find that when I login via CPG, it logs me into phpBB, redirects me to CPG as it should, but I'm no longer logged into CPG. Going back to phpBB shows that I am indeed logged in, it's just no longer registering with CPG. Thinking I removed something I shouldn't have when tinkering with the themes, I reinstalled both themes with their original files, but this hasn't fixed the problem. I've rechecked all the settings and, as I thought, nothing has changed. Any thoughts on what the heck I did to make it stop working? Is it possible that it can work on one computer but not another? (That's the only other difference I can think of.)
Try deleting your cookie (or changing coppermine's cookie name in coppermine's config, which will have a similar effect). For details, post a link and test user account (non-admin).

That worked, thanks! Wish I had tried that before resetting all my themes. Oh well.
