Try clearing your cache and cookies, logging out and back in again, using a different browser, and accessing Marketo from a different network, if applicable.
When does the error occur (editing an email, creating a program, etc.) and is it reliably reproducible?
Thank you, AnneMarie. I have already tried clearing cache/cookies. I could use Firefox, but I prefer Chrome. I haven't tried a different network. I mainly get the error when editing campaigns.
Performing those actions helps to isolate the issue to help identify whether this is occurring on Marketo’s side or is localized to your device. If the issue persists after trying those, I recommend submitting a case with Support, so an engineer can review the log files during the time of the error message.
