Were you trying to send a curated mailing only to encounter a 500 error when loading the VME?
Were you able to select articles on the content step of a Single Mailing Campaign, as in the illustration below?
If you were, but after clicking the orange carat, the next screen gave a 500 or timeout error, it was most likely an issue caused by the content within the body of one of the currently selected posts.
Unfortunately, the post causing the error cannot be included with the mailing, but the other posts can.
To solve the issue and get your mailing out to your subscribers:
Rebuild your campaign, selecting one post at a time until you cannot load the editor. When the editor does not load, you have found your culprit.
Alternatively, if you suspect which post or posts may be causing the issue, you may wish to start by leaving the suspect post(s) out first.
As always, if you have any questions, please don't hesitate to let us know. You can find all of our great support resources and how to get in touch with us via email, chat or phone on our Support Page.
