Yes, it seems the tool is assuming that because they are internal links they should not be nofollow.
The tool does not have a brain that knows what your intentions are, you do. If you know better, ignore those warnings and consider them more as āshould look into theseā messages rather than āmust fix theseā messages.
As both @Mittineague and I have tried to explain, if you have chosen to make those links nofollow then there is nothing to fix; nothing is broken.
SEMrush is drawing attention to the fact that you have the nofollow attribute on internal links (which is unusual but not wrong), in case you have done this by accident and want to change it. If you are happy with those links being nofollow, then you donāt need to take any action.
I created nofollow to whole site to avoid OBL getting my juice , if entire site is nofollow is it practicall to find so many links ,or what is way forward
I see no other option. Either you need to live with things as they are, or you need to change them. How did you set all links to nofollow in the first place? Is this a WP setting? (I donāt use WP.) If so, can you find an option to set only external links to nofollow?
fyi im using https://wordpress.org/plugins/seo-internal-links/ which we can set external* links to nofollow/dofollow ,this is not WP setting but plugin is putg nofollow on my internal-link so dats issue
In that case, it would seem that the plug-in is not working correctly, and I would suggest that you contact the author for support. (There is also a link to a forum.)
Other than that, I can only suggest you remove the plug-in.
Personally, I would steer well clear of a plug-in which has only seven reviews and three of them are bad; that is not an indication of quality, IMHO.
In that case, are you sure that you have set it correctly to allow links to your own domain?
Nofollow whitelist ā Allows you to specify a whitelist of domains that you do not want to add ānofollowā attribute to (for example for your own sites).
