Cakephp 1.2 page goes white on any form submission

I have a local cakephp 1.2 app which was working fine last night. Currently when I submit any form, the resulting page goes white/blank.

This is what I have tried:

• Cleared browser cache
• Commented out my memcache in core.php
• Turn debug on to 2, in 开发者_如何学Pythonwhich I get a couple of warnings (always had them), but no errors and the sql debug stuff
• Cleaned out cache of models and persistence in tmp folder
• also played with setting security from medium to low

Any ideas would be helpful?

You should keep that debug mode at 2 while developing. That helps a lot.

What are the warnings? If the code is correct, there shouldn't be any warnings. I don't think it's a problem with browser or cache. What's in your controller method? You can also do a $this->log($variable,'logfile') anywhere to debug. The output will be in tmp/log

Maybe you should upgrade to 1.3, I'm not sure if all my advises would work with 1.2
