Screenshots

Desktop (please complete the following information):

• OS: ArchLinux
• Browser Firefox
• Version 138

Additional context

• Actually should have been fixed in module 'lxml.etree' has no attribute '_ElementStringResult' error since v0.45.18 #2312
• _ElementStringResult is only found in:

$ grep -ri _ElementStringResult /usr/lib/python3.13/site-packages/changedetectionio
grep: changedetectionio/tests/__pycache__/test_xpath_selector.cpython-313.opt-1.pyc: binary file matches
grep: changedetectionio/tests/__pycache__/test_xpath_selector.cpython-313.pyc: binary file matches
changedetectionio/tests/test_xpath_selector.py:    assert b'_ElementStringResult' not in res.data # tested with 5.1.1 when it was removed and 5.1.0

I am confused where the problem comes from. 😕
