For some time BASE 1.4.5 has been giving me tons of log warnings from deprecated php functions for example:
PHP Deprecated: Function ereg_replace() is deprecated in base/includes/base_state_common.inc.php on line 184
PHP Deprecated: Function ereg_replace() is deprecated in base/includes/base_state_criteria.inc.php on line 255
PHP Deprecated: Function ereg() is deprecated in base/includes/base_signature.inc.php on line 142
There is a patch available to fix this issue at http://sourceforge.net/tracker/?func=detail&aid=3009648&group_id=103348&atid=635584
To apply the patch simply download it and use in BASE folder with:
patch -p0 -Nu < patch_base_1.4.5_php5.3.txt
