Hi Ash,
I’m using the latest version of Google Chrome on Windows 7. The same error happens in the latest Firefox.
The link text itself shows '>
in front of the text ‘Export current 301’s to CSV’.
To clarify: when I manually go to the page in the link (wp-admin/admin.php?action=bulk301export) I can download the CSV file just fine. Therefore, something must be wrong with the link (not the receiving page).
Upon checking, the other urls in the same spot don’t work either. They show /wp-admin/<?=%20plugins_url(%20%27301-example.csv%27,%20__FILE__%20);%20?>
or something similar in the address bar.
I suspect it might have something to do with WPML, as I am running a site with two languages. Unfortunately, since it is a live site I can’t experiment too much with it.
Other plugins are Contact Form 7, Contact Form 7 Honeypot, various WPML (offical) extentions, Regenerate Thumbnails, Simple 301 redirects, Simple Page Sidebars, Types, WordPress Charts, WordPress SEO, WP-Mail-SMTP. Like I said, I cannot experiment by disabling since most are essential to the (live) website.
I hope this helps!
