Request failed: unable to verify support for request URLs

Installation
#1

I’ve installed Concrete on my webserver. But I get an error about the precondition Supports Concrete request URLs. The error message is: Request failed: unable to verify support for request URLs.

It seems to be in the area function getHtml()

$ajaxFailErrorMessage = json_encode(t(‘Request failed: unable to verify support for request URLs’));
…
$(document).ready(function() {
$.ajax({
cache: false,
dataType: ‘json’,
method: ‘GET’,
url: {$url}
})
…
.fail(function(xhr, textStatus, errorThrown) {
setWebPreconditionResult({$myIdentifier}, false, {$ajaxFailErrorMessage});

…

Anyone an idea how I can meet this precondition?

I am trying to run concretecms with PHP v8.0.15.

#2

This often indicates that the php extension ‘curl’ is not enabled on the server.

#3

Just asked my provider, unfortuantely the PHP extension curl is enabled.

Any other ideas?

#4

Yes, ask them to check that php extension mod_rewrite is enabled

#5

just got the answer: Yes, mod_rewrite is enabled.

#6

Hmm, a bit of a long shot but try setting the PHP version at 7.4 to see if this is a PHP version 8 problem.
If the installation completes you could then switch back to PHP 8
ALSO ask if the fileinfo extension is enabled.

#7

Ok, switched to 7.4 and still no luck. I have created a PHP Info File so you can have a quick look at the config of the PHP:

Why is there a concrete-cms-9.0.2 folder in the root of your site?
When you extracted the folders and files into your root you should have moved everything out of the concrete-cms-9.0.2 folder into the root and then deleted that empty concrete-cms-9.0.2 folder.
The folders in the root should be as follows:

application
concrete
packages
updates

and the files should be:

composer.json
composer.lock
index.php
LICENSE.TXT
robots.txt

I changed the default root to that path. But hey I really want to give concrete a try, so I have moved everything to the root, deleted all files which is not in your list and I still have the same problem :frowning:

The only thing I can suggest now is that I take a look in your cPanel for you.
If your happy for me to do that send me a private message with the server address, username and password.

Hey, I think I just discovered another issue, which could relate to this one. I have modified the requesturl.php to accept the “fault” and I could continue. But on the next site it came up with another error message: is_dir(): open_basedir restriction in effect. File(/var/lib/php/sessions) is not within the allowed path(s): (/var/www/vhosts/hosting151828.a2eb8.netcup.net/:/tmp/)

And I fiddled a little bit with my browser and I found this error in the console area of my browser:
http://www.crazykoodaa.de/index.php/install/web_precondition/request_urls/20?_=1646489072967

If this is the main issue, then maybe there is a way to change the path?

#12

I finally found the solution… I changed 2 settings in my cPanal under the website. From the DOCROOT to WEBSPACEROOT. See the 2 pictures below. Now the error was gone (even after editing the changes in requesturl.php back to normal) and my page is running :slight_smile:

Thanks for the help
