EE 5.3.0

When I go to the Add-Ons section of my control panel I get this error:

Parse error: syntax error, unexpected '.', expecting ',' or ';' in /.../.../public_html/.../ee/EllisLab/Addons/rte/ext.rte.php on line 19

When I go to that line in the file (which I haven't touched and would never dream of messing with), I can see that the line in question has no issues. It's just a $docs_url with an expressionengine url as the value. There is no unexpected '.'

I have used a url path to get into two of my plugins directly, bypassing the Add-Ons list page, and they seemed to work fine. It's just the Add-Ons list.

Any ideas?

Hrm, well that line in ext.rte.php in the 5.3.0 release is:

var $docs_url       = DOC_URL.'add-ons/rte/control_panel/index.html';

So based on that error, I would assume the DOC_URL constant is not yet defined, or isn't being type interpereted as a string.

So try this:

var $docs_url = '';

If the pages loads, this smells like it could be a bug; start by using a search tool to determine where that DOC_URL constant is defined, and make sure it is getting a valid string value. You could also try hardcoding that variable to a valid value and if it works, it's another hint that DOC_URL isn't being defined.

  • Thanks for the response. In my ext.rte.php file that variable actually is not using the DOC_URL. It is var $docs_url = 'https://docs.expressionengine.com/v4/add-ons/rte/control_panel/index.html'; In any case, I removed it as you suggested and the page is now loading. I checked to make sure nothing was happening to the rich text editor in other places that I'm using it, and there seems to be no problems. This is odd because I do NOT touch the EE core classes, so I don't know what could have changed to cause this.

  • I have faced this same error and checked to find this constant defined in any files. I have found the two files where this constant is defined. 1) system\ee\installer_5.3.0\controllers\wizard.php 2) system\ee\legacy\libraries\Core.php Screenshot: prntscr.com/ray4i2 Commented Mar 3, 2020 at 14:42
  • I had the same problem Installed Version: 5.3.2 Build: 22-4-2020 I did edit the file found in /ee/EllisLab/Addons/rte/ext.rte.php and changed line 19 into var $docs_url = 'add-ons/rte/control_panel/index.html'; . The error was gone, have been working since then intensively with the site without problems. Reported this as well to Robin Sowell.
