For the second time to reboot my system the application that not denvolvi
opens not load and the message
Load filed PHPMaker project file! Parse error line 320 chater 21 <fild name = fld date
How to proceed
Try to open the project file in notepad, make sure the project file (an XML file) is well-formed, test it by renaming it as .xml file and opening it in your browser.
If it is well-formed, post the line 320 (few lines above and few lines below).
Or you may open the backup project under <Documents folder>\PHPMaker\Backup to see if you can open it and reuse it.
