My website, [login to view URL] was working fine till 24th March 2017, Friday. Since Saturday morning, Jetpack and Google Analytics from monster Insights stopped working. I updated php version to 7 from CPanel. The issue did not resolve. I reverted back to Php version 5.6. Jetpack plugin was giving error with regards to SSL certificates, but the certificates are working fine. Then, website started not loading on my home wireless network. Mobile site and website works on outside networks or cellular data networks. I uninstalled both Jetpack and Google Analytics from wordpress admin on my mobile. However, the issue remain and now, i'am unable to upload or install any new plugins as well from outside network. So, 3 thing to be checked and resolved:
1) website not loading on my home wireless network
2) Unable to install or upload any plugin from Wordpress Admin page. Error is "An unexpected error occurred. Something may be wrong with [login to view URL] or this server’s configuration. If you continue to have problems, please try the support forums"
3) Check if there are any other html/code/script/wordpress errors and fix them
I will provide my hosting network login and wordpress admin details but i need a thorough check and resolution to this issue. The website should load correctly both on my home wireless network and outside like before.
I only change i did was change php to 7 from 5.6 and changed it back. and uninstalled and deleted jetpack and monster insights google analytics plugins.
There is a substantial amount of traffic visiting the site everyday so the urgency is of most importance.
