Testing defender on a MS dev project
Scan Hangs at 57.6% (Analyzing wp-content files)
Around 55% it flashes an undefined message prior to moving to 56.7% before it hangs (let run for several hours).
Did the basics, disabling plugins etc.
Tested on another site with same basic configuration (same theme framework, child theme – same basic plugins, same hosting service) and no problems.
Access granted, just in case.
