DB Error in OJS 3.2.0.0 - illegal mix of collations

Software Support

Hi all,

After installing the OJS 3.2.0.0, all the HTML galleys were not viewable. It does not affect the PDF galleys. Please see the snapshot below:

I upgraded the OJS3.2.0.0 via web/cpanel softaculous package. How can I make them appear again? What should I do to my database to make it viewable?

Thanks!

Hi @neuroscirn,

This is a MySQL error message, not an OJS error message; you might find some helpful guidance e.g. on StackOverflow: mysql - Illegal mix of collations (utf8_unicode_ci,IMPLICIT) and (utf8_general_ci,IMPLICIT) for operation '=' - Stack Overflow

If you were able to resolve the issue, please post the resolution in case someone else runs into it.

Hi @asmecher,

Yes, again you brought me to the solution. Basically, I used pHpAdmin in the cpanel to change all “tables collations” and “tables columns collations” of the ojs database to utf8_general_ci and everything miraculously works again in the database!

All my problems are solved with the OJS 3.2.0.0. The interface and editorial activity tab is great!!!

Cheers~
