 * You have version 1.7.24 installed. Update to 1.7.29.
 * when I try and carry out this upgrade I get the following fatal error:
 * Fatal error: Uncaught Error: Call to undefined method Blocksy_Screen_Manager::

 * after the update I can’t get my header configured correctly – the colour is incorrect
   and I cannot change it. So I’ve restored from backup to before I did this update.
 * I tried it yesterday and today, both time causing the fatal error.

 * unfortunately the header is still not correct.
 * It looks correct in appearance > customise, it looks correct if I view it logged
   into wordpress, it however doesn’t look ok if I look at it on another computer
   or in incognito browser. so I’ve had to restore the backup again.

 * I thought it would be cache so I tried emptying it but it made no change. I’ll
   disable the cache, disable the companion, upgrade and see if I can make it work.
 * I’m quite busy today with work stuff – but i’ll try and fix it tonight. Thanks
   for all your help 🙂

 * Seems to be a problem with “WP Fastest Cache” – if I disabled that plugin then
   the header works as expected. But that creates then issues with my css animations!
   So I’ve disabled that as well, but now everything is updated and working 🙂 I’ll
   implement a different cache and see how it goes.
 * thanks for all your help.

 * I purged everything from wp fastest cache, deleted all the minified css and html–
   then rebuilt the cache. Everything working, cache, css animations, everything!
   consider it solved 🙂 thanks for help.
