Debugging mode: blank page!

uli · 2008-04-28 16:54:22

This leaves me completely clueless: I’m getting blank pages in debugging mode (no source code).
In testing mode I get "Tag error: <txp:chh_if_data> -> Textpattern Warning: tag does not exist", though chh_if_data is installed, is active, and the use of plugins is checked in the prefs.
Can somebody please give me a kind hint on how to solve this? I’ll gladly provide any necessary information! Thanks in advance!

EDIT
Seems to be caused by Zend. Turning it off did the trick. (MAMP -> Preferences -> PHP)

Does disabling all plugins help?

Can you post your full diagnostics?

Any clues in the Apache error/access logs?

Also, if you have shell access to that server and assuming a command line PHP version is present, try running the main index.php file using the command php index.php

So, something is segfaulting. Either an apache child or a PHP process. Let’s try to find out which one:
If you have shell access to that server and assuming a command line PHP version is present, try running the main index.php file using the command php index.php and see if that throws an error.

This is way too much expected ;] Can you break that down to single steps, please, if necessary?

variaas · 2008-04-28 17:59:20

@uli

Have you seen this post

uli · 2008-04-28 18:10:50

variaas, no, I haven’t. But this is more than I can handle. Would you be so kind to point me to the passage that you think could be important for me?

uli · 2008-04-28 18:20:29

Ruud, can I combine a path to the command line from any info I can grab from phpinfo()?

uli · 2008-04-28 18:29:40

Alright, Apple’s Terminal-app is drag’n‘drop capable. So I could get any path. Which “main index.php” shall I grab?

ruud · 2008-04-28 19:37:32

In your terminal:

php /Users/Uli/Sites/txpdemo.dev/index.php

or

cd /Users/Uli/Sites/txpdemo.dev
php index.php

uli · 2008-04-28 20:11:01

I’m running backups quite regularly. Which part of my local installation seems to be concerned? Is ist possible, that the database got corrupted? If so, which table?
Or are my guesses completely wrong?

ruud · 2008-04-29 17:33:26

Can you try installing a separate fresh copy of TXP (different directory, using a different database table prefix) and see if the problem is reproducible.
If the problem doesn’t occur there, you could try to make both installs more similar, for example by installing the plugins you have in the other install, copying templates (which can be done by copying the corresponding tables from the malfunctioning TXP install), etc, up till the point where things begin to break.
