I have “Custom Wizards” and “OneSignal” plugins installed.
How can I check error logs? Could this be an issue with the Custom Wizard plugin? If I remove the plugin and rebuild, will I lose any of my Custom Wizard data?
The Custom Wizard plugin is probably to blame, but I could be wrong. Try disabling the plugins one at a time (starting with the Custom Wizard) and rebuilding Discourse.
@codinghorror - your edits are incorrect. The plugin that was at fault was OneSignal, not Custom Wizard. I just had another issue (error on Custom Wizard) and had to comment out the OneSignal plugin again to resolve it. It seems like OneSignal is doing something funky.
