Following the advice in https://wordpress.org/support/topic/update-480-messed-up-homepage seems to have done the trick. How strange!
Have the same problem over and over again. Thanks for the hint with the other post!

It seems you have been able to solve the issue.
If so please mark this topic as ‘resolved’.

Actually it’s not solved at all 🙁 Unticking the blacklist temporarily reprieved the problem but then it still went back to doing it and so I’ve had to turn the plug-in off.
@kmcharityteam
Ok, if you are still interested in solving this you could:
Activate the iTSec plugin.
Change WP_DEBUG from false to true in wp-config.php file.
With this change in place hopefully an error msg will start displaying on the blank page.
If there is still nothing on the blank page check the server error_log for any errors.
Don’t forget to set WP_DEBUG back to false in wp-config.php file once you are done testing.

Hello Dwinden,
When the white screen occurs nothing shows when debug is set to true.
This is what happens in the error log however
oursite.co.uk [Thu Jul 16 08:45:13 2015] [error] [client IP:36233] AH01215: PHP Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 72 bytes) in /home/sites/oursite.co.uk/public_html/wp-includes/wp-db.php on line 2221
You seem to suffer from the nr 1 issue with the iTSec plugin.
As a temporary and quick solution disable the Schedule Database Backups setting in the Database Backups section of the iTSec plugin Settings page.
Then you’ll need to analyze\investigate why the backup is running out of memory. You may have some log table(s) in your database with 10000s of records that are pointless to backup and makes the database backup too big for the iTSec plugin Database Backups code to handle.
Deleting the 10000s records or excluding that log table will help complete the backup.
Sometimes increasing the php memory limit will solve the issue.
But in any case it will be a matter of time before the issue returns …
Best and permanent solution would be for iThemes to rewrite\optimize their Database Backups code.
Alternative is to use another plugin for creating backups.

Thanks Dwinden, I’ll try that 🙂
