Recently I had to do the upgrade from Wordpress 2.2.3 to 2.5.1 in my Granadeiros Azulinos blog. After following all the steps of the detailed upgrade process - backups, disable plugins, copy new files, update and reactivate plugins, reapply customization of themes, etc.., the blog worked well in the new version! Great!
However, one strange problem: after creating new posts in the administration panel (Wordpress dashboard), or after leaving comments in the blog posts, I got a completely blank page. Afterwards, the problem got worse: the Wordpress admin panel became totally blank, nothing worked!
After a full day’s search, I had already tried several solutions and suggestions, but nothing … Changing themes, deactivating and uninstalling all plugins, physically deleting the plugins from their directory, even making changes in the Wordpress database. I was already tired, thinking that the problem could be related to PHP’s memory use. I was thinking about contacting my hosting provider to see how PHP was configured.
Suddenly I found, lost amid a tech blog’s comments, a simple suggestion that was crucial to solve my problem: to check whether my wp-config.php file had any blank lines in the end!
Unbelievable, but this was the problem: when doing the upgrade, I had some things changed in my wp-config.php, including the introduction of the new SECRET_KEY option. After the upgrade the file, I had left some white lines in the end, and those lines were responsible for the file not being loaded correctly by Wordpress PHP scripts…
So, the only thing I had to fix was, to remove the blank lines from the end of the file and GOTCHA! Everything was back in order again! Nice one!

Thank you! This almost fixed everything - I had to go delete all the blank lines from my funtions.php file too. Perfect now.

Infelizmente comigo não resolveu.

Opa, parece que deu certo sim, só tive que aguardar alguns minutos depois da modificação. E fazendo um adendo, não somente retirei o espaço em branco, mas fechei a tag do php.

Hi,
It’s a strange setup really when other cms systems always seem to have a debuging tool available that can tell you where the program is erroring. Zikula, Zencart and Joomla all have very effective debuging tools available which can save days of tracking is something goes wrong.
It seems that Wordpress is the only cms system that does not have a system debugger available.

I replaced functions.php with the original theme file and it solved the problem!
Thanks.
