Cannot save when ready to generate the code

It’s been like 3 weeks that I want to save and it gives me " 500 Something Went Wrong" What is going on? It’s been so long time and still, not working, if it won’t be fixed within a couple of days I will cancel my account. SO ignorant

Same issue here. Haven’t been able to save a new gallery in weeks now. Can someone from Tubepress reply if and when this will be fixed?
