Hi Denzel, Thanks so much for your feedback. I have disabled all but the plugins that came with the site and a pay-gate plugin (payfast) i need for the ecommerce shop. I still have some issues though (site is still not as mobile friendly as i’d like it to be).
I also picked up lots of errors though when i ran a CSS validator test – what can i do to sort this out?
Did this occur due to the many plug-ins?
Was it the 4.3.1 update of wordpress that made it worse?

See link with errors..!

Thank you very much.
