Blank page for WordPress feed: what to fix?

[Bluej]

Hi —

I just moved a WordPress site from a temporary URL to a permanent location. I re-installed WordPress using a script installer. (originally I tried to copy the development files, but the server connection wasn’t reliable enough, and transfers kept failing).

Every thing is working except the feed: http://motivationfactor.com/feed. It was causing a 500 server error before — now it causes a blank page.

I think there is something wrong with my theme or installation. Can you help me narrow it down?

I’ve tried
-disabling all plugins
-checking wp-config.php and removing a blank line at the end
– checking index.php in my child theme folder for a blank line or coding error.

What else could I do to find the problem?

Correction: The blank page is at http://motivationfactor.com/news
(I need more sleep!)

If it isn’t on already, try turning on PHP error reporting. If there are any code errors, it will then tell you.

OK — since I don’t have access to php.ini to turn on error reporting, I’m using Error Log Monitor WordPress plugin By Janis Elsts (wonderful).

The warning logged is:

PHP Warning: call_user_func_array(): First argument is expected to be a valid callback, ‘analyticscode’ was given in /usr/local/pem/vhosts/100758/webspace/siteapps/WordPress-4603/htdocs/wp-includes/plugin.php on line 406

Somehow I don’t think that’s related.

well, in case it helps anybody, in Solution to WordPress Blank Web Pages without error Display, Sataya recommends adding this to wp-config.php:

define(‘WP_DEBUG’, true);

It worked great to display an on-page error message. You have to turn ‘true’ to ‘false’ as soon as you’ve noted the error, because visitors will see it too. Very handy.

My errors on http://motivationfactor.com/news are:

Notice: add_option was called with an argument that is deprecated since version 2.3 with no alternative available. in /usr/local/pem/vhosts/100758/webspace/siteapps/WordPress-4603/htdocs/wp-includes/functions.php on line 2910

as you know in this case i can help you if i know exactly what you did! so just try to re-install it my friend :-) one year ago same problem occurs to me(errors on administration panel) and i found out i should remove all blank spaces in the beginning of the function.php file!

[Bluej]

Thanks @mostafghanbari

The error message refers to a file I didn’t touch, wp-includes/functions.php

I will go check for extra spaces again….

[Bluej]

OK I found the problem.

There was an extra index.php file in my theme folder, with // silence is golden as the content. Removing that fixed the problem for me.

Thanks for all the advice – it’s all good.
