I updated PHP 5.6 to 7 and MySQL 5.5 to 5.7.
Everything was fine in the older versions, however since I updated the server some plugins such as: Custom 404 page, gregorian2jalali face problems. Some pages goes blank and the Inspect Element, Console section nothing shows. up. For example, if I activate gregorian2jalali plugin, User Profie page doesn't show up.
Also in the Custom 404 page plugin, the following error comes up in 404 pages:
A Question2Answer database query failed when generating this page. A full description of the failure is available in the web server's error log file.
There was a related question for an earlier problem here: When adding page link, database query error occurs.
In the Apache Error Log, a message similar to this message comes up:
PHP Question2Answer MySQL query error 1146: Table 'qa.qa_options' doesn't exist - Query: (SELECT 'options' AS selectkey, title, content FROM qa_options) UNION ALL (SELECT 'time', 'db_time', UNIX_TIMESTAMP(NOW()))
Also, there was an earlier problem here at this question: is there a way to manually create the database tables ?
Now that the plugin is not updated, how I can fix this problem ?
