Problem Dreamweaver dont show html and preview

Which version of Dreamweaver do you have?

Adobe Apps on M1 Chip

Does your Mac volume and files have full read/write/edit permissions?

If it happens on all files and only on the new computer, can you try moving the files again from your old computer to the new one. It is possible there was a corruption that happened during the move that caused some strange issue.  Same thing could be said about having a corrupt user profile from the move.

First thing I would try is migrating the files again if you have access to the old computer.  After that if you are still having issues try creating a new user profile on your new Mac and open the files from there and see if the problems persist.

Friends, it happens with all files and I already uninstalled and installed again and the same problem happens. On my old mac dreamweaver works normally and opens the same files I want to open. I do not know what else to do? My new Mac has the M1 pro chip, not sure if there may be some incompatibility

• Did you restart your computer after installing DW?
• Does this happen with all files/sites or just certain ones?
• Does the document contain valid, error-free code? https://validator.w3.org/

Is this happening with all files or just some files?  Have you also tried restoring files from a different time machine backup? I'm wondering if something happened in the transition and if you could roll back to an earlier image.

unfortunately it didn't work!

Can you try going to Dreamweaver --> Preferences --> Interface and choosing a different theme to see if the same issue persists?
