I have built an LMS on wordpress and I am facing some issues now. I need someone to help me with it. These are the issues I am facing with it at the moment that I cannot fix:
1) Login issues: At the moment, anyone who logs in gets redirected to the wp-admin page automatically. This causes alot of issues as the page is not available for non admin members
2) Speed up the site: I have tried to activate the W3 total cache plugin for my site but it screws up the site. My site is quite slow now as a result. I also have a CDN but I have not implemented it to the site yet. Need help in that.
3) Redirecting the subdomains
4) Study my site and let me know what else can be done to improve it.
This is all the help I need. If you think you can do this well, do let me know!
