You can visit the demo site of Magazine New pro – there is no such issue with the theme

Regarding updates, Updates available only show for active licenses. The current version of the theme is 1.0.9 and you are using 1.0.2

For some time the ability to filter blog articles by tag, category or collection has been broken. Visually, I see a split screen/blank white page. Inspecting the source, I see this error:

There has been a critical error on this website.

Any ideas? If I change my website’s theme to one of the WP out of the box themes like twentytwentyfour, that feature works.

I no longer have an active license- I purchased it in 2019. But when I check my license, it says there are no upgrades available, so it doesn’t seem worthwhile to renew it as there appear to be no updates to it.

Thanks,
Jeff

Is there any way for me to actually access this with this theme that I’m missing?

Alternatively, some of the things I’d specifically like to do are,
1) Change the layout so the content takes up the full margins (no background image/padding)

2) Remove the image/link in the footer to the Magazinews Pro site – I paid for the pro theme, I shouldn’t be forced with this watermark

3) Change the color of the Primary and Secondary menu bars
