Phpmaker Composer generated autoload.php does not exist


I am trying to compile the php code generated by phpmaker

after compilation application show this message

Composer generated autoload.php does not exist. Make sure you have run “composer update” at the destionation folder on your development computer and uploaded the “vendor” subfolder.

but generated code is working with apache without any issue and i can see autoload.php in the file list too.

Kindly suggest the solution


If PHP displays “missing file” errors and warnings like " php failed to open stream ", you may need to mark files in the File Manager (select your files, click File Properties and turn this option on: Unpack the file(s) to virtual memory at startup ).
Or keep the missing files as external files.
