when i install the coppermine is work but when i try to SAVE NEW CONFIGURATION it show me this errors msg said "" is an XSS and was blocked.
anyone help please
If this is a brand new install, I recommend deleting all of the files, dropping the Coppermine tables from your database, and installing 1.4.2.
why got to be 1.42 why cant i use this 1.30 for my site
If you want to stick to 1.3x, upgrade to 1.3.5, then. Earlier versions have had security flaws, including an XSS one.
If you want all the latest features, like uploading GIF images when using GD2, you should upgrade to 1.4.2.
