If you are receiving a 404 error or very slow load times while attempting to edit a template or campaign or upload/paste HTML, take a look below at some possible troubleshooting. If none of the below applies, please reach out to firstname.lastname@example.org.
Code "Too Large"/ Junk Code
Especially for those that upload or paste HTML (rather than use the Drag-and-Drop Editor), you may want to beware of "junk code". This means code that appears to do nothing at all and is not related to your content. It may look like the example below:
The culprit for junk code may likely be a browser extension. For example, the browser extension Grammarly (while very helpful to catch grammar issues!) is a common offender to add code to a file you run through their service.
In this case, you will want to turn off your browser extension/ app and re-upload your code to fix the error or upload time, which is faster than trying to find and delete all of the "junk code".
