Try to refresh your page for mising icons. Hmm it seems I've to delete the old language files because AceSEF 1.5 has just English lang included.

@Edgar
No problem, we'll add extra 10 downloads to all users

Thanks Denis that fixed the icons.

I'll manually delete the Dutch language file then Cheers for the swift reply!

Im still having a lot of problems with the 1.5 upgrade. I did just upgrade to the most recent version from the AceSEF upgrade panel. I can now view and edit the configuration ( I did have the Class 'AcesefSitemap' not found when I first upgraded)

However, I cannot edit any sef urls. When I try to edit them, there are no buttons or any css formatting in the modal popup, and there are no save/apply buttons in the edit screen anywhere if I dont use the modal popup ( ie: select a sef url, go back to the top of the screen and click edit ). Saving or applying does not work. I see this message at the bottom of the screen:

Fatal error: Class 'AcesefSitemap' not found in /yadda/yadda/yadda/administrator/components/com_acesef/views/sefurls/tmpl/default_edit.php on line 285

I did an upgrade again from the Upgrade page and the "Configuration" and "Quick Edit" problems are resolved. Thank you

Yup, that's correct. I also upgraded again and things are working fine!
