Hi
I have two extensions. Both work perfectly in the front end, but in the back end in the form I am getting an error when using PHP 8.0.6. The following is repeated 4 times.
Warning: SimpleXMLElement::xpath(): Invalid predicate in C:\xj_sites\2_dv\libraries\src\Form\Form.php on line 1366
Richard
Steps to reproduce the issue
Install TDOC Facebook module - http://www.tdocplus.co.uk/tdoc_j4_dev/tdoc_fbk/mod_tdoc_fbk.zip
Expected result
Form no messages
Actual result
Error messages plus form which shows fine. See screen shot.
System information (as much as possible)
PHP by apache 3.3.0 compiled 6th April 2021 running under Windows 7 Sp 1
Noted: that the system info page seems to have got lost in J4 !
Additional comments
Works fine in PHP 7.4.16 on fast hosting direct.

Your XML is invalid as there is no closing
</config>- but Im going to assume thats where you copied and pasted to GitHub -
Line 1366 relates to the name of a field, and a quick glance at your XML I see you have a spacer with a name of
<div style="color:#fff; font-size:12px; font-weight:bold; padding:3px; margin:0; text-align:center; background:#333333;">Dimensions</div>
Its a hunch, but try replacing that with just Dimensions and see if the error goes away.
I cannot replicate this issue (although I have PHP 8.0.10 installed - the latest and only secure version in 8.0.x series)
Phil.
First of I am absolutely delighted that my extension works in 8.0.1.
Next is thanks for the location of the information. Here it is:

Will do some testing and see what happens.
a) changed as you suggested - and now I have a just the word "Settings", but of course not highlighted
b) I got the code from a Joomla web site on structure of xml files. But I normally make a note of these things - NOT in this case ! See here: http://tdocplus.co.uk/0a_Empty400/face-book/facebook-display-instructions-and-code
Will install apache 3.3.0 on my laptop and see what that says - it may be a win7 problem

Hi
Installed php 8.0.6 on windows 8 lap top. Problem persists
Then installed php 8.0.10 . Problem persists
Guess then this is now a bug in Joomla 4
Phil - how is your error reporting - I am set to Max. Cannot actually change it as I get an Invalid Field error .
Richard
I write code for a living. My whole stack is set to always display error error, warning and notice.
To be totally sure I added
error_reporting(E_ALL);
ini_set('display_errors',1);
Just before the line in the warning in your screenshot and still no warnings were shown.
Im on a mac, we need someone here to test on windows, I dont have access to windows. I think @brianteeman still uses windows, maybe he can test and replicate?
When I dump out the paths they look ok to me
Hi
I think the two errors may well be the < and > around the format.
I used to write a lot of code in Clipper, and the CA_VisualObjects. see wp.tdocplus.co.uk. But that was many years ago. It ended up a nice stable product, and people still download and use.
But PHP has never been high on my list, tho I did write some scripts for server side processing of transmittals notes and rfi/tq's etc. No css so it was not exactly pretty... the heart attacks ... 74 and well retired
But I FEEL it's a bug. Maybe an MS interpretor somewhere ...

I am delighted !
It might mean that I have dodgy code repositories as it happens on all four of my web sites in J4 in W7.
