Login failed with PHP 7.2

[IngoBelka]

Hello Everybody,
I have a fresh installed system with:

• Ubuntu Server 18.04 LTS
• Apache 2.4.29
• PHP 7.2.5
• Yellow 0.7.3
  ** YellowCommand 0.7.5
  ** YellowCore 0.7.3
  ** YellowEdit 0.7.17
  ** YellowImage 0.7.3
  ** YellowLanguage 0.7.8
  ** YellowMarkdown 0.6.8
  ** YellowUpdate 0.7.10
  ** YellowThemeFlatsite 0.7.5

I get "Login Failed" even if I could set all the initial data of the fresh installation. I read, that Yellow should set a cookie for a working login, but there comes not a cookie. Setting cookies is allowd for the ip of this server. I have no idea, what I can do now.

I addition to that I get:
ERROR checking updates: Plugin 'update' requires cURL library!
but dpkg sayes that it is installed```

ii  curl                                  7.58.0-2ubuntu3.1                 amd64        command line tool for transferring data with URL syntax
ii  libcurl3-gnutls:amd64                 7.58.0-2ubuntu3.1                 amd64        easy-to-use client-side URL transfer library (GnuTLS flavour)

Any help is appreciated.

Have you installed Yellow using the setup wizard provided by the edit plugin or on the command line?

Regarding Curl: You need the appropriate PHP module in addition to the actual curl libraries. Try installing the php7.2-curl package, (might vary on your system) this should solve the updater problem.

I just did an update from command line using
php yellow.php update force

with the result:

YellowBlog 0.7.4 YellowSearch 0.7.2 YellowWiki 0.7.4

and now I can no more edit pages:

I have also this issue.

Just make PHP version from 7.2 to 7.1 or 7.0

@schulle4u
"Installing is unzipping one file and you are ready to go. Just give it a try. If you have to read the instructions first, then we have done something wrong." ;)
Thats what I made, and it is really not trivial to install, without reading instructions, and nevertheless it doesn't work.
The php curl package I installed now, but I had to install the php zip pakage too. I could update the installation then, succesfully.

But a login is not possible.

@Rustapo
I think the ball is in the field of Datenstrom, to make Yellow working with Php7.2.

@IngoBelka
Yes need wait New release of Yellow CMS to working with PHP 7.2 and higher.

But I give suggestion to resolve this issue.

[IngoBelka]

@Rustapo

After some debugging it looks like something is broken in the PHP 7.2 version that comes with Ubuntu Server 18.04 LTS. Here's a short test case that works fine with previous PHP versions, but it doesn't work with PHP 7.2.5:

Script:

<?php
	echo "PHP ".PHP_VERSION." ".PHP_SAPI."<br>\n";

	$token = "ABC";
	$lengthBytes = strlenb($token);
	echo "$token $lengthBytes ".($lengthBytes!=0 ? "ok" : "error")."<br>\n";

	testString();
	function testString()
	{
		$token = "ABC";
		$lengthBytes = strlenb($token);
		echo "$token $lengthBytes ".($lengthBytes!=0 ? "ok" : "error")."<br>\n";
	}
	
	function strlenb() { return call_user_func_array("strlen", func_get_args()); }
?>

Result:

PHP 7.2.5-0ubuntu0.18.04.1 apache2handler
ABC 3 ok
ABC error

As a workaround disable the PHP OpCache. For example add the following to your .htaccess file:

php_flag opcache.enable Off

[IngoBelka]

Hej Mark, I switched back to PhP7.2.x and set
php_flag opcache.enable Off
Now I can login with PHP7.2, too.
While upgrading the system this morning I saw that Version Php7.2.6 came on my system, but this didn't changed the behaviour. So, I'll leave the opcache setting as you suggested.

After install Yellow v0.7.5 then update online, it seems to work now

After looking at the PHPInfo from my webhost:
https://www.legtux.org/phpinfo.php

PHP is v7.2.8-1

If someone can test with the same PHP version, please confirm ..

[markseuffert]

Good news, Ubuntu has updated to PHP 7.2.10 which finally includes the bugfix:

PHP 7.2.10-0ubuntu0.18.04.1 apache2handler
ABC 3 ok
ABC 3 ok

Should be working now.

[BsNoSi]

I can confirm 7.2.10 as working.
