I am facing following issues.

1.
I have a module for generating pdf invoice, once installed I get this error:
Fatal error: Cannot redeclare array_insert() (previously declared in /home/turnstonellc/public_html/system/vendor/BurnEngine/library/Utils.php:988) in /home/turnstonellc/public_html/system/library/mpdf/includes/functions.php on line 45

Can we disable the loading of mpdf from the theme ? or could you implement some testing to check if library is already loaded to not load it ?

2.
The Option are showing strangly as after installing Related Option, Live Prices, Product Option Image PRO the product page is not behaving properly, there is a QTY field on please advice.

4.
