Blank Category Page - "use Tygh\http;" Issue

Multi-Vendor Questions
1

So I noticed I had a blank category page today. Errors shows:

Notice: Use of undefined constant opt_961 - assumed 'opt_961' in /home/user1/public_html/shop/app/addons/price_calculation/func.php(83) : eval()'d code on line 10

Fatal error: Unsupported operand types in /home/user1/public_html/shop/app/addons/price_calculation/func.php(83) : eval()'d code on line 10

That line in that file is the use Tygh\Http; issue Any idea what could be causing this or a fix? This is an add-on for calculating custom pricing. Luckily I only have a handful of those products that use this but still needs to be fixed ASAP. Not sure how long it has been that way or what would cause it to stop functioning.

Have you contaced the price_calculation addon developer? It will be faster to solve the problem.

Agree, the error is caused by 3rd party addon

I have, but wasn't sure if it was something obvious that I could easily sort out since it was working before.
