Hi, i got the same problem. My error message is about another line : www/blog/wp-includes/wp-diff.php on line 290
My post is very long : i ask myself if yours is a long post too or a short one ?
My idea is that the script wp-diff.php have to parse all the words to make revisions… I’ll try to make the same process in a local installation and i’ll increase de max execution time.
All feedbacks we’ll be nice ??
