Problem when running the experiment online

I have the experiment in the Builder, but when I press the button to run it online, this window comes out, and I cannot upload it:

Traceback (most recent call last):

wx._core.wxAssertionError: C++ assertion “!(flags & wxALIGN_RIGHT)” failed at …\src\common\sizer.cpp(2098) in wxBoxSizer::DoInsert(): Horizontal alignment flags are ignored in horizontal sizers

I don’t know what to do. I hope you can help me out.

What version are you running? Going to the location specified in 2020.2.4, the ALIGN_RIGHT flag isn’t there - between 2020.2.0 and now I’ve removed a lot of these so it may just be a case of installing the latest version to fix this

The version is PsychoPy 2020.2.2. I didn’t get it. Shall I just install a new version?
Thanks for helping!

Ah yes that’ll be it, we’re on 2020.2.4 now and I think there were a few more of these I removed in .3, so updating to the newest version will fix this :slight_smile:

Thank you very much! That solved the problem!
