Php update to 5.6.19 - Template Problem

Hi there,
I updated my local installation from php 5.3.x to 5.6.19 (Mysql 5.5.5) because my host will update from 5.4 to 5.6.x on March 13th. Works fine so far, but changes to your jp-hifi template can't be saved anymore. Therefore I can not use my own template style anymore ( www.avpfister.ch ). Other templates still do work (native templates, or ict apollio for example). Is there a template update or a workaround?
Thanks and best regards
Ralph

Hello,
1.) Delete your Browser and Joomla cache
2.) Update the Warp framework

Hello,
thanks for your tip. Updating warp framework solved the problem, template can be saved now. But updating joomla "weblinks extension package" to version 3.5.0 gives following error in the template header:
Warning: DOMDocument::loadHTML(): Unexpected end tag : ul in Entity, line: 4 in C:\xampp\htdocs\avpfister\templates\jp-hifi\warp\src\Warp\Helper\DomHelper.php on line 47

After uninstalling weblinks extension package 3.5 everything works well again.
Hoping for a solution, best regards Ralph
