This is not really a bug I guess(!?), but anyway: text field for keywords/tags seem to accept only inputs up to about 250 characters. This number is reached by about 20 tags of average length, or less when tags are long words. Unfortunately words are cut off, when characters’ limit is reached.
This behaviour is reproducible in PivotX 2.3.7, 2.3.9, 2.3.11, tested with MySQL 5.1 – 5.5 and PHP 5.4 – 5.6.
I know there is no active PivotX development anymore, but is it possible to tweak tag field’s limitation or make it unlimited?
