White, Blank Page After Trying to Post?

By Widge - posted 04.27.08 @ 5:01 am

So here was my problem: after updating to 2.5.1, I started to get a blank page after updating or posting something new. It would come up to post.php and nothing. Granted, the post itself would be indeed updated or posted (although my Meta Data via Headspace2 wasn't being saved), but beyond that, it was baffling.

I had seen this problem before when I was tapping my resources while still on shared hosting. So I knew this had to be something do to with PHP limitations.

I increased my PHP memory via .htaccess (adding a "php_value memory_limit XXM" line where XX is the amount) and that didn't seem to do the trick. It was while I was looking at my server via FTP that I figured it out: my Sitemaps Generator plugin was taking forever to build the sitemap. I knew this because I could see it happening as I refreshed my server directory. So, poking around in the options, I saw it:

"Build the sitemap in a background process (You don't have to wait when you save a post)"

Wunderbar. Click that and my posts were going through. Granted, when I checked out the Sitemaps options I was being told the map wasn't finishing. So I upped the execution time limit to 120 seconds and that so far seems to have done it. I saw a bunch of people in the WordPress forums having this issue for a multitude of reasons and if you found this post then good on you--Googling "blank page wordpress" or the like is ever so much fun.

Why was it working on 2.5 and not on 2.5.1 without these tweaks? Dunno. I have had the image upload whitescreen problem again, even on 2.5.1, but it appears to be intermittent. And I can't quite seem to figure out when hitting Save on a post just saves it and when it sends me (on the same screen/tab) to a preview. I'd love for that to go back to where I can preview when I say preview and save when I say save. Also, it used to be that the checked categories appeared at the top of the list--why did that change? Many, many mysteries.

Update: I think I pinned down my image upload problems...check out my solution here.

    Apart from problem with comments, people can also get a blank page on commenting because some of their comments are marked as spam by blog owners. Akismet sends a 403 error along with blank page in this case. You might want to check that out.

    Jason: No offense, but since the post in question has nothing to do with comments but rather with putting up a new blog post, you yourself might be spamming. But I'm going to split the difference and remove your URL and we'll call it good. Deal?

    [...] I found the problem and everything is working properly again and it was simple as hell to fix.  I just disabled the Google sitemapping plugin.   Maybe they can have a look at it when they have time.  For now I won’t be using it. [...]

    I had a similar "blank page" problem when I tried to install a plugin that did not play well with the other plugins I had installed. I was able to recover from it and bring the site back up. Here's what I did to fix it.
