There are many other 'media upload error' threads out there. Posting again as none of them have resolved the issue for me, which persists after numerous fresh installs of WP.
Issue
Random errors when uploading new media to the media library using either the standard 3.9.1 upload interface or the browser uploader. I either get just the little red tag at the top of the screen, or the following error against the uploading media entry at the bottom:
Fatal error: Maximum execution time of 30 seconds exceeded in /home/content/77/12052677/html/wp-includes/class-wp-image-editor-imagick.php on line 355
I have spent time on the phone to my host, had them look at /tmp and php.config for media upload file limits etc all to no avail.
I was not having this problem in 3.8.2. It is possible that host have updated something, and so there is a version conflict somewhere. It is possible the problem is purely Wordpress. I suspect the latter, and therefore hope the WP Wizards on this site can help, as the problem is a total blocker for me on client sites.
Any help very much appreciated I'm at a brick wall on this one.
