I've been trying to send e-mails in the usual way I always do this morning - importing an e-mail from MailerLite and editing it slightly before sending - but once I've composed my e-mail, I get an error message when I try to go to the next step, which means I can't save the e-mail (I also tried pressing save content and had the same issue) or send the e-mail.
I get this error message each time...
"Internal Server Error

Please contact the server administrator at [no address given] to inform them of the time this error occurred, and the actions you performed just before this error.
More information about this error may be available in the server error log."
I'd really like to send my campaign today, so please let me know what's happening.
