Hi,
I had to repost this problem again as i had previously posted the same issue regarding update from version 2.0.15 to 2.0.16 but not getting any resolution for 1 week now. I managed to upgrade from 2.0.15 to 2.0.16 using extension install based on the advice by the Paul Frankowski (support).
Subsequently, i reloaded the site and this time there was an update to 2.0.17 and i followed Paul Frankowski 's advise again and i got the same failure no matter which approach i take. I am so tired of creating so many sites for Joomshaper's support staff and also performing various diagnostic tests. So much time has been wasted. Anyway, for everyone's information these are steps i did to upgrade. If anyone else can help please help!
(1) Initial Extension Update Page
(2) After Updating System - Helix Ultimate Framework Extension
