When I have a long description (say few K), and output it at archive using [wpv-taxonomy-archive info='description'], page just crashes. Sometimes it shows WP error about crash, and sometimes it shows some broken shortcodes. Are you aware of such limitations?
I'm pretty sure that custom wysiwyg field will work, but I'd prefer to use standard description.
Looking at the source code for the wpv-taxonomy-archive shortcode it really is quite simple, it just gets the queried object which identifies the current archive and returns the description.
The only potential problem I see arising from Toolset is that it passes it through a debugging filter first.
Can you test on your site with an even simpler version of the shortcode that skips the debug filter?
Register the shortcode [archive-description] with the following:
The only other gotcha here would be if you include this shortcode inside a conditional statement, where it is known there are limitations on the length of text that can be included as the content of the shortcode.
