found in the last version of Webuilder 2020. Some times my PC blocked, i close webuilder with some HTML/PHP files opened and i force an hard reset. when indows 10 is ready i re-opened webuilder but the last file on which i was working is lost, appear only jhidden chars!
If i use an editor like Cudatext tell me it doesn't recognize the file formaat, i choose "open anyway" and the file is opened.
Can you try to add similar options if a file isn't recognized? thanks!
