I haven’t heard from you so I send you my latest response.
Hi Mark, I have deleted my current plugin. Then I uploaded from your file, installed and activated with same result. Still HTTP 500 ERROR.
Actually the whole website shows the error message. Immediately when activating the plugin. Not only the product page(se) in question.
It will still be activated for 20 min from sending this message. Then I have to make my website available again.
Sorry I meant 1.2.6… That’s the one I am using. See prtscrn
