Errors after updating help

[Yormas1995]

Hello group. After updating abantcart I have been experiencing problems.

*When opening some of the articles I get the following error image
as sometimes it opens but does not reload.

*The bottom part of the page also appears disorganized

The first photo I attached is of the error in the article and the second of what I get disorganized. As well as the bottom part of the banner that was above where

Help me with the testimonials section. It no longer has the rotating effect that it had before. All the text appears placed there as if it were a paragraph.

Hello.
Please check your AbanteCart error log for last errors

Hi, I've solved the problem. The thing is the following. I was looking at the Abantcart demo and the design is perfect, but mine is not right. For example, the testimonials are all disorganized, and the About Us section is also disorganized. I haven't been able to place the banner because it's all out of place. Everything happened since I updated it. Everything was great before the update.

try clearing your browser cache and check if all your plugins are compatible with the new version

Yes, in reality, it's not easy to upgrade to the latest version. Those who have been working on this for a long time can get things back on track, but those who are new to this are finding it hard to get the site working normally with default theme (bootstrap5), Blocks don't work, some images no longer appear, product zoom works on some images and not on others, many things out of place. It's really frustrating to upgrade and have your site broken, they should do a post explaining what we have to do to make everything work perfectly.

I have to install abantecart again but in a folder on the hosting server and there I go little by little editing it until I have it to move it to the public_html folder. The truth is I have to do everything again since what I had with the previous version was damaged almost everything. ! how truly sad

Is there any official guide to help fix issues when upgrading to the new version, especially regarding the default theme (Bootstrap 5) and content blocks?
