Great Plugin and Great Support

by gnode·2 months ago

I usually don’t like leaving reviews on wordpress plugins mainly because it has come from a plugin developer who leaves begging messages all over my dashboard for reviews. Thankfully these guys don’t do that. The plugin is great but this review is about how they care about the people using it. I posted a message asking if they would be adding support for Turnstile and the feature was implemented quickly. I’ve been asking Elementor to put support in for Turnstile for over a year and they still can’t be bothered to implement it or even put it on the development list. The team behind WP24 Domain check are on the ball and I really appreciate them implementing this so quickly.

NOT WORKING – Always gets an error

by tutay·1 year ago·3 replies

I always get this error: fsockopen(): Unable to connect to whois.crsnic.net:43 (Cannot assign requested address)

Tried to contact the Sharedhosting but they won’t open this port. Why does this plugin need to configure the server? Completely not working.

Very good

Invalid message not displaying

by jooie98·3 years ago·1 reply

I have a small problem with entering an invalid domain name in unlimited domain check type. The invalid message show as usual when I first entering an invalid domain name, after that I entered a valid domain name and it also show a modal as usual. After that, everything started to go wrong. When I entered an invalid domain name, the plugin didn’t remove the div with id ‘dc-result-‘ of last result modal show it cannot do changes with div area with that id to show an invalid message. Can you modify that or instruct to modify that?
