I’m having the same problem with WordPress SEO 1.5.0, and I have been told by my host that it is not a memory problem in my case. Whenever I’m trying to upload an image larger than approx. 1000×1000, I get this error:
An error occurred in the upload. Please try again later.
The image doess get uploaded in wp-content/uploads, but is shown as corrupt in the Media Library, and I cannot add it into any post. The only workaround is resizing the photo.
This also happens with W3 Total Cache, which is another plugin by Yoast, and XML Sitemap & Google News feeds. Any idea how to fix this?
