WordPress 2.7 Blank Page Problem (Upgrade & Fresh Install)

Final bit of information. If I use the admin panel’s User functions to create a new user, by using the “Add User” link, the resulting user account gets the white/blue/blank screen. If I create a new account by using the registration link off the login page (having logged any current account out), the account created this way is functional.

OK this is ridiculous. These accounts, when created via register, are okay only so long as they are subscribers. When changed to author, suddenly the site admin goes blank; change them back to subscriber and the site admin can be seen again. This is true if I change the account to anything other than subscriber and then back again.

The View Source in FF shows me as stopped along here when I get the blue screen of death, every time I check:
<script type=’text/javascript’ src=’my-wp-site/wp-admin/js/plugin-install.js?ver=20081210′></script>
<script type=’text/javascript’ src=’my-wp-site/wp-admin/js/media-upload.js?ver=20081210′></script>

Not that that seems especially helpful.

This is silly. Going to go back to 2.6 and rebuild my users db there. *grump*

This issue of blank pages and user creation persists in 2.6 now. I had no problems before the 2.7 upgrade, and it’s really marvellous to see this bug transport itself back down to 2.6…except that this seems to be happening on MY blog, which takes out the amusement factor fairly quickly.

Thoughts? Would really love some. I had thought to create new user accounts, then migrate the info from the older corrupted ones into the new ones. but the new ones themselves don’t work once you take them out of subscriber status, in either 2.6 or 2.7 now. I am stumped at this point.

Restore your backed up database and restore your backed up files and it should work again.

But the topic is not going back or blank page with 2.6 it’s “WordPress 2.7 Blank Page Problem (Upgrade & Fresh Install)”

I changed from hosting company and am now with MediaTemple which solved my problem. Their auto-installer works perfect and the manual installation as well.

For those that are debugging their php settings; these are the settings used by MediaTemple on php4 and php5 that work flawlessly with wordpress 2.7.

PHP4
PHP5

For those still having problems; I think you can better open new topics detailing the problems. I’m setting this topic status to resolved, despite the solution was changing hosts.

I have read this whole thread while having the same problem described. After upgrading my database I would get a Blank Page on the home page.

While this may not be the same problem detailed in this thread, I think that many people may have this exact problem

THE SOLUTION to my problem was that I didn’t place my old theme (from 2.6) in to the new installation (2.7). This is why I was getting the blank page. Your site theme selection is stored in the database, even after the upgrade.

TO THE DEVELOPERS you should probably make the upgrade process change the theme to the default theme and then administrators can change the theme back after the install.

just my idea
thanks for a great application

Hopefully this info will be useful to someone having the blank page problem:

I was having the “blank page” problem sitewide. I could not view the site or log into the dashboard. I run WP 2.7.1 and PHP 5.2.8. I read this thread along with several others and I ended up going into the WordPress database using PHPMyAdmin to disable my plug-ins by hand. Under the wp_options table there is an “active_plugins” entry which you can edit in order to disable plugins without having access to the dashboard. If you look at the structure of the list of plugins you’ll see how much text to delete in order to disable them.

It would probably be a good idea to back up your entire database before attempting any of this, BTW.

After I edited and saved the entry in PHPMyAdmin, the blank pages went away and the site loaded fine, as well as the admin side. You can then re-activate plug-ins one by one to see where the problem is. In my case it was very strange… I’m currently still building the site so it’s not public yet, so nobody had been on it. One day it worked fine, then I didn’t even touch it that evening, and the next morning the blank pages had invaded. If it was indeed a bad plugin, I’m not sure what activated it or caused it to start making trouble.

But anyway, <phew>… crisis averted. My thanks to all the participants on this forum for their good documentation of these errors.

Just wanted to let everyone anyone else having this problem know, I started getting this blank page.php problem about half an hour ago and just found that it was the plug-in WP Widget Cache, which I had installed earlier today.

The strange thing is that I have WP Widget Cache installed on another WordPress blog of mine (both sites are running WP 2.7.1) and it doesn’t break the admin.

If anyone wants to look into this, I don’t know how much this helps, but the site that works with WP Widget Cache is:
https://pecuniarities.com

The site that WP Widget Cache breaks is:
https://carnivalofpecuniarydelights.pecuniarities.com

My [very obvious] suggestion is, if this problem started recently and your WP had worked previously, deactivate plug-ins you’ve recently installed in reverse chronological order.

Most users probably know this already, but hope this helps someone new.

I have the same problem as Taxonomy had, but wasn’t able to resolve it. No major issue, as it’s all on localhost, just a huge bummer.

Just for anyone who runs into this problem, I was recently upgrading an older WordPress install and ran into this blank page problem, could not get into the control panel or anything.

wdln’s solution above is correct, the blank pages is likely caused by out of date plugins that are not compatible with the latest versions of wordpress. To fix the problem go into the wp_options table of the database and in there there is an entry for “active_plugins”, delete its contents and that will disable all the plugins, then you will gain access again.
