I keep getting the 500 error when trying to install an app. I’ve tried different browsers, clearing cache and cookies, I’ve tried the Android app as well. This started last night and I’m not sure why.

I started getting the issue last night when trying the marketplace connect ebay integration. I’ve uninstalled that right now and it seems to work.

I’m getting this error attempting to install Shopify Marketplace Connect. Based on your fix, do I have to uninstall something else to fix this?

thanks
