When I try to access "Manage SEF URLs" I get the following error message:

Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 47298561 bytes) in /home1/airturn/public_html/libraries/joomla/environment/response.php on line 208

Help! I need to export my JoomSEF URLs!

I'm trying to change JoomSEF to Professional mode, but when I select it and click on "save" or "save and close", nothing happens and JoomSEF stays in basic mode. What am I missing

I'm trying to set "Use sitename in page titles:" to "no", but when I click "save" or "save and close", nothing happens.

Same problem happens when I try to go to Professional mode - I click on "save" or "save and close" and nothing happens.

I just purchased the latest version of JoomSEF and am trying to upgrade from 4.3.2. In the upgrade tab, I'm selecting the com_joomsef4.zip file, but I'm getting the following error messages:



Your free updates period has expired.
Component Install: Custom install routine failure
Error updating component.


Help!

I'm trying to upgrade from 4.3.2 to 4.4.4. I went ahead and purchased version 4 just now and tried installing it with the Joomla Extension manager, but that didn't work. I don't want the option to automatically upgrade to the non-paid version. Help!!

I just purchased the JoomSEF extension for RSTickets, but that doesn't appear to be compatible with the new RSTickets!Pro help desk module. Please let me know if a new JoomSEF for RSTickets!Pro can be made asap - can I refund my purchase and exchange it for an extension that's compatible with RSTickets!Pro??
