"We're sorry, something went wrong..." problem everytime I publish a project.

Hi Marko

sounds like there may be a corrupt slide in your file. Have you tried creating a new project and importing the project in.  If it still closes down, try Isporting in 10 slides at a time and test publishing - it will help you isolate where the corrupt slide may be.  Look at interaction slides and slides with images they can sometimes be problem slides.

I have tried importing the whole project to a new one and I still got the same problem.
The point is that it is kinda complex course, lasts around 2 hours, more than 200 slides and I needed more than a month. First I will try to divide and publish scene by scene and I will tell you the result later.
Thank you very much.

I have tried and I have found that all the slides from one scene are causing problem (other scenes are still empty, slides created as placeholders but nothing on them), there are more than 50 slides in the same scene and when you try to publish each slide separately I got the same message.
Still confused how to fix this, those slides are also most important part of the course.

So of the 50 slides on the one scene did you trying 10 at a time to see if it makes a difference? Happy to take a look if you want to upload just that one scene with content

I have separated my whole presentation on half, than the half on quarters and with that method I found out that the slides from once scene are causing problems. I tried importing half of the slides from that scene, it was causing problems, than I tried the other half it was also causing problems, than I tried one slide only from the scene, I saw the error again. Tried another slide, saw the error again.

Anyway, I solved this problem, I found the issue, the silliest one I have ever seen. The reason for the error was that on the master slide, in a text box I used special character from the character map, I used this: ▶ I just removed it from the text box and I published it without any problem.

Thank you very much,

Glad you sorted it out Marko

This conversation helped me so much! I had the same issue, so I saved a copy and selectively deleted slides. I was able to narrow the problem down to three slides, and then specific pieces of content in those slides. Once I replaced the offending objects, problem solved. This file was upgraded from a previous version, and I guess not all of the content faired well in the conversion. Easy fix though-- thank you! 

Glad to hear it Melanie. Love seeing when these older threads are still helping users out. I appreciate you popping in to share.
