Hi Guido,
I run several sites on WAMP and I use the Validator plugin for a quick check on pages, although it will sometimes show syntax errors that I cannot track down. The ‘maxlength’ issue showed up with this plugin. I leave debug.php running and also like to get rid of PHP notices to prevent filling the log file.
For active sites I run validator.w3.org/nu/ to check HTML, CSS and SVG. The ‘maxlength’ threw an amazingly long explanatory list of attributes:
Error: Attribute maxlength not allowed on element input at this point.
From line 780, column 4; to line 780, column 105
label>↩ <input type="hidden" name="vscf_captcha_hidden" id="vscf_captcha_hidden" maxlength="75" value="312" />↩ <i
