Make sure you have run composer update. If you do not know what is "composer update’, read: https://phpmaker.dev/doc/sysreq.htm#composer.

You better

  1. Click Tools → Delete Template Cache,
  2. Delete all files in your project file and generate all files again,
  3. Make sure composer update is run successfully after generation.

I don’t think your composer update was successful. Did you see the “vendor” folder?

You may try:

  1. Delete composer.lock and “vendor” folder in the project folder,
  2. Generate all files (including composer.json) again,
  3. Open a command prompt or PowerShell at the project folder,
  4. Enter “composer -V” to test your composer installation, make sure there is no error message.
  5. Enter “composer update” to update. Then you should see a “vender” folder in the project file. In the “vendor” folder you should see many subfolders and an autoload.php.
  6. In the project folder, you should find a “src” folder, in which you should find the HttpErrorHandler.php.
    If the autoload.php is generated by composer correctly, your app should find the class HttpErrorHandler.
