Please help with class_core.php Error

Change you config file to use "127.0.0.1" for the MySQL server rather than "localhost".

Hello and thank you for your reply.

May I ask why do you think this might help?

Thank you guys for your replies. We are running vbulletin 4.2.5 PHP7.

PHP 7 what? Did your host upgrade to version 7.2 recently? That might be an issue.

Hello, thanks for your reply yes we recently upgraded to PHP 7.2

Errors persist and new ones develop:

Database error in vBulletin

mysqli_real_connect(): (HY000/2002): No such file or directory

Feels like slow certain death if this continues.

Should I edit my config file to use "127.0.0.1" for the MySQL server to see if this will help?

vBullletin 4.2.5 is not compatible with PHP 7.2 unless something has recently changed.

Ask your host to downgrade your PHP version to 7.1

[Wayne Luke]

You will not be able to use versions of PHP newer than 7.1.X with vBulletin 4.2.5.

Currently, the only version of vBulletin that is compatible with PHP 7.2.0 RC5 and higher is vBulletin 5.3.4. We have no plans to update vBulletin 3.8 or 4.2 to be compatible with PHP 7.2.

Thank you Wayne.

Just a quick update on this error. After four weeks of trying to figure what was going on Wayne and the others were right this was definately a server problem with our host which they finally admitted MySQL is being restarted during cpanel updates and DB queries made during this time fail. We are running PHP 7.0. What version do you recommend for vbulletin 4.2.5?

[Wayne Luke]

PHP 7.0.X should be sufficient. You want to run between 5.6.30 and 7.1.9.

Thanks Wayne.
