Replace preg_replace with preg_replace_callback.

[thmtht1612]

In php 5.5 preg_replace is deprecated. This leads to error messages being posted on the site and in the logs.

I am not too good with php, so I am wondering if someone can create an update. It seems to be the Sources/Load.php file that contains several preg_replace functions.

You should upgrade to current version, 1.1.x went eol some time ago and is no longer supported.  Other option is to downgrade php to 5.4 (also eol and unsupported).
