Course Will No Longer Preview

Hi Dustin, is that the May 19 2020 update? I'm on the latest and I'm not experiencing any issues with preview or publish? If you'd like I can test your SL file on my desktop to determine if the issue is isolated to your machine or is a problem with the file?

HI Dustin, I'm having the same issue - would appreciate if you could update us if you get a resolution. Cheers

Yep, that was the May 19 update (Build 3.40.22208.0).  I've tested some of my other courses, and some have the same issue, and others don't.

Those that have the issue worked prior to the update (which I downloaded on 6/6) , but not after.  I made no changes to those courses in between the time that they previewed and published properly, and the time I installed the update.

Another thing happening with this issue is that I can't play a slide using the Timeline.  When I select the small play button in the lower left corner of the timline (or press Spacebar) nothing happens.  My mouse cursor turns into a blue spinning circle acknowledging that I selected the play button, but it times out after maybe 10 seconds, and the slide never plays.

Will do Chris.  I submitted a ticket to support this morning so hopefully we'll get this resolved before too long.

Hi - update from me. I rolled back to the May 5 version and it appears to be working fine. Phew. Might be worth a try, Dustin. All the best. 

Just saw a post from another user who also looks to be having issues with preview after an update. It provides some information on changes they made to get around the issue. Might be useful for Articulate to track down the issue: https://community.articulate.com/discussions/articulate-storyline/solution-for-white-blank-screen-in-storyline-360-preview-and-frozen-first-slide-in-review

Rolled back to the previous (May 5th) version like @Chris Burke did.  Everything is working fine and dandy again.

Thanks Chris!

In other news, Articulate Support did some troubleshooting of the course, but wasn't able to replicate the error I ran into.  They sent me a video demonstrating that the course worked when they published it to Articulate Review.  So we didn't figure out why this was happening to me and not to them.

However, in the thread @Sam Hill referenced where someone was experiencing a similar issue due to this latest update, the @Anastasia Nikitina mentions she used special fonts for a dynamic page counter that was placed on her master slides, and that the page counter used a special font.  I also did this in the courses which were experiencing the preview/publish error, and I noticed the that Articulate Support Specialist's version of my course did not have any of my special fonts (likely because they didn't have them loaded on their machine).

Could be something.  I'd take some time to test this theory, but I have a pressing deadline that needs my attention now that I can work on this course again. 

Thanks for the help all! Have a good one!

Hi @Dustin, definitely worth passing on the info about fonts to Articulate. Sounds like it might be having trouble rendering certain fonts affecting the preview.

Agreed.  Done and done.
