    Hi Mikko,

    After update to ver. 4.0.4 on site running PHP 7.0 I had the following message:
    Fatal error: Uncaught Error: Call to undefined function mysql_connect()
    I could not find the mysql_connect() function in any plugin files, but found instances of mysql_ including the following:
    relevanssi_index_mysql_columns relevanssi_mysql_columns and relevanssi_form_mysql_columns in several files.
    If possible, reverting to PHP 5.6 is a temporary workaround to fix the the site after crashing.

    Relevanssi does not use mysql_connect anywhere, Relevanssi does all database interactions through the $wpdb interface. Is it possible the function call is in a different plugin?

    Hello Mikko,

    My apologies and thank you for your quick reply. When I didn’t find mysql_connect in the plugin files, I should have realised that the error was not from your plugin, even though it indirectly triggered it. I thought the anomalous error message was cause by a glitch related to the use of mysql_ functions, but it was late and didn’t have time to check further.

    Today I dug deeper into the issue and finally found the cause. I had tested the plugin on a development site on a WAMP localhost server where PHP had been updated recently from PHP 5.6 to 7.0. Although all the extensions were installed and I had had no other fatal errors, I had omitted to update the extension_dir= in the php.ini file. Thus the error was caused by WAMP not being able to find the required file for PHP 7.0.
