Username and passwords wrong again and again

Read what I wrote about commenting certain lines of code. I am sure that you have an old version of MySQL (MySQL is consisted by the server and the client, each one may have different version).
Even if you comment the lines I write you will stuck exactly afterwards because of the old version. You can comment again the next lines and finally install elxis but your server environment  won't be good for Elxis.

I don't understand why you don't believe me! I am an experienced PHP developer - I have worked on Mambo/Joomla sites for a number of years, and have developed a very sophisticated billing component. I run 2 dedicated servers with MySQL 4.1.22. I am not a newbie - I know the difference between a client and a server. Never mind, I'll step through the code myself and fix it.

I did nt said that I don't believe you. The problem that you have, was, especially last year, a very common problem because many servers had mysql 4.0 and the symptoms were exactly the same (line 92/94). If it is not a mysql version issue it might have something to do with database permisions, host or even, as sirigos said, with the database name, user or passowrd (i.e. strange characters). I can not be sure if I don't see it.

If you wish give me ftp access to your site to install Elxis 2006.4 for you by myself. I understand that you are an experienced user but what seems a huge problem for you might be 2-3 minutes work for me as I know Elxis very good and that does not mean that I am smarter or better developer than anyone else. I just now where to focus my attention and how to solve these kind of issues. Send me a personal message with your site URL, access to your ftp (in order to be able to debug the installer) and database login info to install Elxis for you.
