"impossible to save email configuration"

[gerroon]

I get the exact same error as described in the forum posts.

This is suspicious:

Compilation failed: internal error: previously-checked referenced subpattern not found at offset 728 at \/volume1\/Web\/owncloud\/3rdparty\/phpmailer\/phpmailer\

Can you please use the issue template https://raw.githubusercontent.com/owncloud/core/master/issue_template.md ?

How did you install/upgrade ownCloud ? Maybe something went wrong when replacing the source code files ?

Dup of #16720

Seems to be a bug in PHP

Looks like a PHP bug: #16720 (comment)

Therefore closing this.

@gerroon Feel free to report back and reopen this if this isn't the case.
