WordPress Admin Panel Left hand Dashboard Issue

To rule out any theme/plugin conflict, try:
– deactivating ALL (yes all) plugins temporarily to see if this resolves the problem (plugin functions can interfere). If this works, re-activate them individually (one-by-one) to find the problematic plugin(s).
– switching to the unedited default Theme (Twenty Seventeen, etc.) for a moment using the WP dashboard to rule out any theme-specific issue (theme functions can interfere like plugins).

Hello, I Deactivate all plugins and switched to different theme
