Save web-pages on archiving services.

5. Actual behavior

I get Error: No enabled archive handler found any time.

A quick glance at load_handlers leads me to believe the error has something to do with path handling. I haven't tested it, but this should resolve the issue:

from pathlib import Path
PATH = Path(os.path.dirname(os.path.abspath(__file__)))
PATH_HANDLER = PATH / 'handlers'

def load_handlers():
    global handlers
    handlers = {}
    # add the path of the handlers to the system so they can be imported
    sys.path.append(str(PATH_HANDLER))

    # create a list of handlers.
    for file in PATH_HANDLER.glob('*_handler.py'):
        name = file.stem
        prefix = name.replace('_handler', '')
        mod = importlib.import_module(name)
        mod_class = getattr(mod, prefix.upper() + '_handler')
        # finally an object is created
        handlers[prefix] = mod_class()

    # exclude all disabled archives
    for handler in list(handlers): # handlers.keys():
        if not handlers[handler].enabled:
            del handlers[handler]
