Update: Anthony did update the version and it worked – but not well enough for the project.
This is the free version output.[easytimetable id=1]
The extended version, which I bought for another project, worked for a day or two, after I built kludges around a few bugs, but then it stopped dragging and dropping, rendering it useless. Just as it did, the maker left for a vacation. So I have to explain to a client that I don;t know why it stopped working, and the maker is gone so until they are back there is a delay.
I will try to figure out why the drag and drop won’t work. Feels like overly agressive IP protection. I’ll see if I can delete everything associated with the plugin from the database and start over, but of course I will lose all the work put into the first development of the schedule.
DANGER WILL ROBINSON!!! WORDPRESS TESTING IN PROGRESS!!! THIS WEBSITE WILL SELF DESTRUCT IN 3, 2, 1, BOOOOOOM!!!!!
Some, perhaps all or most, of the Themeforest themes had jquery errors that caused some problems after the wordpress 4.5 update. The solution is exactly what you would expect – you must get an updated version of the theme from its creator at themeforest, and upload and install it as usual with theme forest themes.
