I have just installed the sitemaps mod, and I love it, but I am having a problem. When I try to change any setting for this mod in the ACP, it does not save. For example, if I go to PHBB SEO tab > Main Configuration and change "Links on Index" to "No," then click submit, I get the "Configuration updated successfully" message, but the setting does not actually update. The Main Config page still shows a "Yes" under that setting and the change is not effected on the front end. (The same thing happens with any other setting change I try.)
What could be causing this? How can I fix it? Thanks!
