Hi,
Thank you for contacting us!
You can try to restore all plugin settings to defaults.
Also, please complete the following steps in order to detect the problem and find its solution:
1) Try to activate a standard WordPress theme for a while (Twenty Fourteen, Twenty Fifteen or Twenty Sixteen) and check if the problem remains.
2) Try to deactivate all of your plugins except Captcha and also check if the problem is still present. If it is not, activate the plugins one-by-one, meanwhile checking, after which plugin activation the problem appears again.
If it doesn’t help, provide the access credentials to your WordPress admin dashboard (with Administrator’s permissions) and the FTP credentials (host, username, and password), in order to detect the reason and find the solution.
Since this data is confidential, maybe, it would be better if you create a private ticket on our support forum (https://support.bestwebsoft.com/). Please include a link to this post, so that we could recall the case immediately.
Sincerely,
BestWebSoft Support Team
