I have a strange problem I can’t solve. I had a WP Network site (formerly WPMU) with two sites working on subdomains. The sites are fairly basic, only 2 other plugins and have been working fine. I have activated the ACF plugin on one of the sites, fresh activation, but as soon as I activated the plugin, the site (front-end and admin) gives a blank white page.
In the error logs I found this:
domain.com [Wed Mar 18 21:13:34 2015] [error] [client 126.96.36.199:36999] AH00124: Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace.
If I remove the ACF plugin, I can see the site again. What could cause this?
I should have said – I’m up to date with my versions, WP v4.1.1, ACF v4.4.1
This helped me realise that ACF was built into my template theme: http://support.advancedcustomfields.com/forums/topic/blank-page-after-activation/
to solve this, I changed my (theme)/admin/acf/acf.php from
define( 'ACF_LITE', true );
define( 'ACF_LITE', false );
Now I can see the ‘Custom Fields’ menu in WordPress without having to activate the plugin.
