Standard troubleshooting procedure:
1. Check for plugin conflicts:
Deactivate all possible plugins: Did that solve the problem?
If it did, it’s a plugin conflict:
Reactivate plugins one at a time until the problem returns. The last plugin activated is the culprit. Report back with that plugin name/link and I can troubleshoot the issue to determine if there’s a fix.
If not:
2. Check for theme conflicts:
With all plugins disabled, switch to a bundled theme (2011, 2012, 2013, 2014). Did that solve the problem?
If it did, your theme is causing the issue. Talk to the theme vendor directly or request premium support to have me troubleshoot the issue with your theme.
If not, it’s an issue with your hosting:
Talk to your host or request premium support to have me troubleshoot the issue with your server.
