I am running JoomSEF 4.2.4 with the K2 extension 3.0.4. The Add Category to URL option for the K2 extension is not working. The only value I can set this to is "All categories". When I select "Only last one" or "No" and hit save it says it saved successfully but "All categories" is selected again.

Here are some screenshots:

I uinstalled the K2 JoomSEF extension and then reinstalled it and it will now save the settings correctly.

I am having this problem again where none of the JoomSEF settings are saving. For example I go to the Configuration tab then the Advanced Tab and change one of the settings. Then hit he Save button and the setting I just changed is reverted back to the old setting. Why is this happening and how can I fix it?

Hi,
There is a problem with configuration in current version of JoomSEF - the values are cached by Joomla if you have Joomla cache enabled. Please disable cache in Joomla while making changes in JoomSEF configuration. This problem will be fixed in next version of JoomSEF.
