No sound and other fixes

The usual reasons for silence, a dry signal, clicks, or a plugin your DAW can’t see.

No sound at all

Is the license panel showing? An unactivated or expired app is silent until you activate it.
Is the input muted? If you see “Audio input is muted to avoid feedback loop”, untick Mute audio input in Audio Setup.
Is the right input ticked? Your guitar may be on Input 2 while Input 1 is the one ticked.
On a Mac, does the app have microphone access? System Settings › Privacy & Security › Microphone.
Does the status bar say NO AUDIO DEVICE? Click it and pick your interface.

Turn off your interface’s direct monitoring.
Is BYPASS ALL on? It reads BYPASSED and the window says CHAIN BYPASSED. Click it to bring the effects back.
Is a section’s power switch down on its tab?

The buffer is too small for the work. Raise it one size, or make the chain lighter: see DSP load.

Logic Pro only loads AU. Run the Mac AU + VST3 installer and look under Audio FX › Audio Units.
On Windows, unblock the ZIP before extracting, and copy the .vst3 into C:\Program Files\Common Files\VST3. Then rescan.
