Website / PHP issues following PHP upgrade

[Oxy]

For those who have unserialize problem

@Admin

The unserialize function was disabled in our PHP 5.4 setup, presumably due to unsolved security problems in that version of PHP. PHP 5.4 stopped getting security in September 2015, so issues like that are bound to occur.

The best way to fix this is to run your website on a newer version of PHP. If your website code supports it, you should just switch to the newest version of PHP (which is 7.4). If that doesn’t work, you can try to use PHP 5.6, or at least the newest version of PHP your site can run on.

If your website really doesn’t work on a newer PHP version, you may want to consider updating your website or switching to software which is still being supported. Because PHP 5.4 is very old by now.
