Perhaps I was unclear.
The Joomla site with the coppermine bridged has been running without problems for a year now. The organization wished to change the domain name from rwori.com to rwone.org.
I installed the new domain name and made the appropriate change(s) to the joomla config file. However, coppermine didn't like the change that I effected to the joomla site and didn't allow members to click on the photo album link and go directly to the coppermine installation (it wanted a login which did no good for it wouldn't accept the login entries). I changed the joomla config file back to what it was previously and everything was fine.
Then I posted some queries when I was unable to discover what needed to be changed in the coppermine / bridge installations.
To this point, everything was still working fine.
Having seen no responses, I decided to load files from directories that I thought might hold the solution into Dreamweaver and then search for the string "rwori".
Either I changed something without knowing or there is a new unknown problem with the server I am using. Not only did the rwori site go down with an error 500 but also another addon domain that has been running perfectly (another joomla with NO coppermine. Was I not paying attention and adjusted files in the wrong directory?).
Since this particular server's support can be downright frustrating, I am checking to see if it is something that I have done. Currently, I am uploading recent backups to NEW respective sub-directories (having renamed the problem site directories in case it wasn't my changes that created this problem).
Now, even if the site wasn't down at this moment, as I mentioned previously, this is a members-only joomla site with coppermine installed within. How would you expect to access this site? Further, why do you need access? Isn't the query simple: when changing a domain name to a site with coppermine installed within Joomla, where should the new domain be changed in coppermine?
