I have a Wordpress website running on Divi theme. I think it is under some attach. When user visit the URL, it gets redirected to some spam site. Below are the things that need to be done
(1) Help me solve this malware redirect attack
(2) Implement some measures to prevent some redirect attack again
(3) I have some 403 issues too. I can't seem to add new plugins, theme and update Wordpress version. I think there is some issue with my .htaccess file. I need this resolved.
(4) I need the speed of my website to increase (Google PageSpeed)
I need someone expert in Wordpress, in particularly with Divi theme to help me with the above. You should be proficient in SEO and website speed optimisation too.
