Are you using a modified version of SMF? The original code can't cause that error message.
Yes, I've done some modifications to SMF.. mainly just changes in template files and additional fields in smf_members for additional profile information.
Way back when, I used to use YABBSE, and I've followed the upgrades as they have come out. With the latest version, SMF 1.1 RC 3, I did the following:
I made a duplicate database for my SMF 1.0.9 board. I upgraded it to 1.1 RC 3. I started out with fresh theme files to install a couple of packages and make changes over the course of a week. I changed Settings.php to reflect the settings for the live database and I tarred all of the files.
I put the live version of SMF 1.0.9 in maintenance mode, upgraded it to 1.1 RC 3, applied the packages and untarred the files.
I've done some testing, and found that with a fresh install of SMF 1.1 RC 3 and a fresh install of the latest coppermine program, everything works fine. But, if I edit the Settings.php file of the fresh install of SMF 1.1 RC 3 to use the live version of my new SMF 1.1 RC3, the error occurs.
I also tried installing Joomla and bridging, but I received the following error:
Warning: Unknown(SSI.php): failed to open stream: No such file or directory in /home/support/vegweb/Sources/Load.php(1790) : eval()'d code on line 2
Warning: Unknown(SSI.php): failed to open stream: No such file or directory in /home/support/vegweb/Sources/Load.php(1790) : eval()'d code on line 2
Fatal error: (null)(): Failed opening required 'SSI.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/support/vegweb/Sources/Load.php(1790) : eval()'d code on line 2
So, I realise now that I probably messed up something, somewhere with SMF, but if you could please, please, provide any assistance, I would appreciate it.
