I was customising a banner on my client's homepage around a week ago, very basic additional CSS on a qode wordpress theme to get the banner looking the way I wanted, achieved that, saved my work and closed my laptop down.
When I got home a short while later, I visited her site on Firefox and the homepage was a mess! Her logo was gone and the theme logo was in its place, the buttons on her homepage had lost all their styling, the banner I was impressed with looked awful and not like the final version I saved, the footer columns widget content had all shifted out of alignment to the left as well as various other styling issues.
I know this is clearly CSS related but error logs are referencing PHP issues, nothing mentioned about CSS and PHP is something I know absolutely nothing about. I've copied and pasted some of the errors and spent some time trying to figure out what they mean but her site has been like this for too long now for me to learn enough PHP to understand these errors and determine whether they could be related to my issue.
Out of desperation, I deleted my theme and reinstalled as I had similar issues following a major update recently and hoped following those steps might solve the problem this time, but no luck.
If anyone has the time and understanding of PHP to scan through my error codes and tell me whether or not this could be related to the problems I've had I would be extremely grateful...
The PHP version is: 5.6.30, Wordpress 5.1.1, the theme is qode bridge version 18.0.8 and these are the latest logs.
The logs are lengthy and look fairly repetitive so I've uploaded them in TXT format rather than pasting here, not sure if that breaks any rules as I'm a newbie to this site.
Thanks in advance to anyone that takes a look...
