This has been asked before but I can't seem to find a clear reason and a solution..
I'm fairly new to Adapt (installed a framework via cli recently) and have been working on customizing a theme. I copied the vanilla theme and made several adjustments (colors, fonts, assets). It works perfectly.
Next step I took was to get it to work in the AT. I made the recommended changes as stated in the docs (as far as they are complete), zipped up the theme folder and tried to upload it into the AT. It didn't work immediatly so I had to try it a couple of times.
Unfortunately my last try resulted in the above mentioned error and it got me locked out of the environment all together. I cannot login anymore. And even worse: neither do my collaegues..
How can we fix this?
