Hi, my name is Greta and my Texas company uses WordPress to develop applications and websites for our customers. I am extremely familiar with WordPress and its core code bases and I typically develop custom plugins and themes.
Creating a custom widget to enable Adsense HTML/Script code to render in the proper sizes, and proving a fix for your non-square image” can be done quite promptly.
Ensuring you have “widget-bars” available above and below your content is merely ensuring your templates are updated for the new widgets.
Happy to do a screen share as well, or provide you with a screen-capture video (which may be easier?). Happy to help.
If you have any questions, feel free to contact me.
Regards, Greta
