I have a custom theme I am using for my website. The area where I write Custom CSS was no longer working so the support staff at Themify instructed me to upgrade the the most recent version of the theme. After doing that almost every page on my site has numerous formatting issues, tops of images being cutoff, margin and padding no longer working as before, font size is distorted(huge).
The support staff where I purchased my theme have told me that the site looks fine to them, but there are obvious rendering issues on the desktop, and the site looks far worse on mobile devices.
To me this seems like this must be some sort of environmental/compatibility issue between the theme, the version of Wordrpress or the hosting environment. That is the only thing that seems somewhat logical to me.
Do you have any suggestions on what I could do to resolve this ongoing problem? My client wants the site to go live at the end of the month and I have been unable to come to any kind of a resolution with the support staff where I purchased my theme.
