I faced a strange issue after upgrade Ari Quiz. When I create any question in admin panel and save it and then try to open for editing I get error 500. I investigated DB tables and found in table ariquizquestionversion that questions created on old versions has structure in field "Data" like that:

But new versions (including latest 3.9.16) creates structure like that:

And when I manualy remove tags <0></0> - the questtion opens normally in backend.
So my question is how to resolve this problem?

Hello,

The problem occurs because on old version of "ARI Quiz" was after upgrade PHP to v. 7.x on your server. Execute the following SQL query to fix this problem (we recommended to create DB backup before running the query):

UPDATE #__ariquizquestionversion SET Data = REPLACE(REPLACE(Data,'<0>', ''), '</0>', '') WHERE Data LIKE '%<0>%'

Just replace #__ with your DB prefix.

If I understand right it can fix some existing records created after upgrade, but what about new questions which I will create in future? Do you mean to execute sql query every time I created new question? I hope there should be another solution.

The latest version of the extension doesn't have this problem. It saves new questions in correct format.

I speak about the latest version - 3.9.16 - it makes questions with wrong format. Just checked again - it does. May be you didn't publish the fixed version yet?

This fix was included a long ago (before v. 3.9.16). Could you provide a temporary access to your J! backend by email so we can investigate the problem?
