Problems after upgrading

[kerimsarigul]

I have faced similar problem before.
This method solved my problem:

PHP Warning: htmlspecialchars()

I was finally able to solve this problem. After migrating from 3.1.x → 3.2.x → 3.3.010 Something happened in the middle that the submission table in the column “locale” showed with NULL values. I changed the values for “es_ES” and in some articles and I did tests and voilà! no more mistakes!. [c37eced4-9903-4ccd-8e68-5fac31608a27] Then it proceeded to change all the values with their corresponding language. Problem solved.

Can you try this?
