SuiteCRM 7.6 - Workflow PHP Deprecated Error

Hello Everyone,

Testing a fresh new install of Suite 7.6, found out an error in AOW Module when adding conditions and actions involving “greater/less than” +/- Date values, the screen of the CRM is displaying next to the actions this message:

Deprecated: preg_replace(): The /e modifier is deprecated, use preg_replace_callback instead in /home1/enjoyint/public_html/asuntos/include/utils.php on line 4363

Then, if I modified and replace with " preg_replace_callback", the displayed error message changes to :

Warning: preg_replace_callback(): Requires argument 2, ‘code2utf(hexdec("\1"))’, to be a valid callback in /home1/enjoyint/public_html/asuntos/include/utils.php on line 4363

Does somebody knows how to fix this?
