This may sound a little odd to post in the Advanced Section, but I have a very big site which is quite mission critical that needs updating.
The issue is, is that when we update the core WordPress, some functionality is broken. Such as the visual editor in the add post, add page sections.
The site is important enough that we are trying to find someone who is very confident in their ability to repair such things.
The issue may be related to this post, but I can not be sure: https://wordpress.org/support/topic/visual-editor-not-working-after-upgrade-to-40
To be clear, what I am looking for is for someone skilled with wordpress on an advanced level, so is able and willing to work hard to ensure a quality update of our whole site. Including plugins, some basic functionality testing afterwards, with issue resolution.
We are happy to pay for the work! We just want to make sure it gets done right! =)
I hope this is an ok place for me to post this, but I have had such great experience here finding WordPress experts to help me with lots of smaller tasks.
