I have posted a few words with definitions and everything seems to work fine in word view, word list view or search page. Plugin works fine as well!
Then I have created a few tags for use with Gnosis.
When I assign one or more JTAGS to a word and save it, then I get: Warning: Invalid argument supplied for foreach() in (my server path)/libraries/cms/helper/content.php on line 121
both in backend and in word page (but not in word list view).
Then, if I remove the tag and save again, the error persists.
My site along with all words, definitions, etc and all tags are in Greek language.
