Hi there !
Please excuse my bad english.
I experienced the problem with the category color just after an update of the AEC. There was more than one problem that I could resolve with those actions:
1) I’ve created manually the missing file cat_colors.css in the folder css of the AEC plugin.
2) I’ve set permission of this file to 777
3) I’ve created a new category with the admin panel of the AEC plugin
4) I’ve updated the other categories
and … Ta Daaaaaa…
Thank you for this great plugin.
PS: I had also fix a bug wich was occured with duration when dates was in french format on more than one day, but I haven’t yet test this version to know if the bug is now fixed in the v1.0.
(WP 3.2.1, AEC 1.0, Host:INFOMANIAK)
Best regards,
Xavier Giorgi.
