Hello, I am currently a Custodian at the Animal Jam Art Wiki. I was editing the page there called Tehbestotakuevah and one day, the editor would only let me use the Source mode since it contains "complex code". I have not added any features that should contain complex code other than columns, but literally, 99% of all pages on the wiki include columns and you can use Classic editor on them. I think my account may just be having issues. If someone can help fix this or tell me the reason behind this, it would be greatly appreciated since I don't know anything about coding.
