Hi,
We tried to reproduce the issue on WordPress v5.6.1, using Yoast SEO v15.8 on the storefront theme (v3.5)but we do not think we are doing it right.
1. We created 3 slides in the plugin and added data to them. See image: https://ibb.co/MBVJGgZ.
2. We then saved and it cleared out all the data. See image https://ibb.co/VHrr8PN.
3. However, the shortcode still renders the slides as expected on the page. See image: https://ibb.co/KmsbPB1.
We would like some more information.
A. Is the issue with #2 above? That the data is getting cleared out after saving?
B. If not, can you elaborate a bit more on the issue or share screenshots? You can use a tool like: https://imgbb.com/ to share the image.
C. Are all your non-Yoast plugins and themes also updated?
D. Can you confirm you are using WordPress 5.6.1? You can check by clicking on the W in the top left and selecting About. If you need to update, please check with your host provider.?Please know that if you are using an older version of WordPress Core you may experience unexpected behavior with Yoast.?This guide explains more:?https://yoast.com/why-we-dont-support-old-wordpress-versions/.
E. From reading the replies here https://www.ads-software.com/support/topic/major-conflict-with-yoast-seo-15-8, it seems like there is some other feature in the SA Slider plugin which needs to be enabled in order to trigger the issue? However, it is not clear to us what that is. Can you elaborate more on if any features of the SA Slider plugin also need to be enabled?
