I have installed NuSphere PhpExpress 1.3.5(Apache/2.0.59 (Win32) PHP/5.2.0) and start my project. I get the next error:

Fatal error: Failed to load encoded file (C:\Program Files\Apache Group\Apache2\htdocs\NRG_Framework_NIN\classes\class_nrg_form.php)
failed to resolve parent class (nrg_window) in C:\Program Files\Apache Group\Apache2\htdocs\NRG_Framework_NIN\classes\class_nrg_mainpage.php on line 19

line 19:
include_once(sprintf('%s%s', PATH_CLASSES, 'class_nrg_form.php'));

Class nrg_form:

nrg_object
|
--nrg_window
|
--nrg_form

What's happening here?

You may want to check if parent classes are available for all classes defined in class_nrg_form.php.

If I comment the PHPExpress extension in php.ini and restart Apache the project runs without any problems. In PhpED no debugging failures.

When I got the error I clear cache via PhpExpress(). Reload the page and the project runs the whole time without any error as long as Apache is running . I think it has something to do with the cache.

Version 1.13.11 installed. Problem solved. Thanks for the quick response!

Many thanks to RanGer. He supplied us with an excellent code sample which replicated the problem so we were able to fix it.
