How to fix "Undefined index: url . . . "

Can anyone tell me how to resolve this issue?
After (1) undating joomla to 3.8.6;
(2) fixing an .htacess problem with redirects; and
(3) enabling the SEFs in global config;

I NOW get this error
"Notice: Undefined index: url in /home4/msmgas/public_html/libraries/CBLib/CB/Legacy/CBuser.php on line 782"

The message appears on the member profile pages & the edit windows.

Disabling the SEFs in global config do not resolve this.

Line 782 is as follows.


It's trying to parse the URL for a CB Menu item. Did you extend CBs menu using CB Auto Actions? If so try unpublishing your auto action. Beyond that I don't know what to suggest as something is incorrectly adding to the CB Menu. Try unpublishing non-core CB plugins 1 by 1 within CB > Plugin Management until the notice goes away.

Kyle, thank you for explaining what is going on. I have been struggling to understand "cause & effect" here & your explanation of the code line 782 helps me.

1) CB Auto actions were not extended. But I disabled the plugin to check.. . not the problem.

2) Your excellent troubleshooting tip helped me locate the cause . . . the error msg disappears when I disable the CB Menu plugin.

QUESTION: The CB Menu plugin version is current; should I uninstall & re-install the same plugin?

NOTE: I went to CB Tools & ran a "check CB plugins database" - the resulting msg read "All CB plugin "CB Menu" database is up to date"

Additional Feedback:

I went back & tested more; the undefined error message ONLY appears on the CB menu item "User Profile". It does NOT show up on such CB menu items as "User Profile Edit" & "User List".

I replicated the "User Profile" in two separate Joomla menus (Main & a side menu) & the error reporting is consistent.

If I disable the CB Menu plugin, the links continue to work & the error msg disappears.

Do you have a valid public and published Joomla menu item to CBs profile page? If not create one and see if that clears it up. A menu item is basically missing somewhere.
