WordPress Failure messages and Error 505. Any suggestions? Thank you. http://www.adrianchambersmotorsports.com.au"
It would be helpful to know exactly what activity you are attempting to perform when you see these error messages, and what specific “failure messages” you’re seeing.
Typically, these types of server error messages are related to your web server running out of resources… e.g. RAM. This is most likely because you are running too many resource-hungry plugins on your site. You can troubleshoot this by disabling plugins individually until you no longer see the error messages. That will tell you which plugin(s) are over-taxing your server.
If your website is being hosted on a cheap, shared hosting plan, it’s likely you’ve reached the upper limit of the server resources allocated to your website. It may be time to upgrade your hosting plan.
Your web hosting provider will be able to access the server logs for your hosting account and tell you more precisely what’s causing the errors on your site.
Hope this helps!
