so my problem is mibew 2.0 for developers, I'm mini-developer,when I try to install ' install.php ' comes this error (screenshot), why?

I'm using altervista for execute php and create db mysql.
on altervista the version 1.6 is working,then in my opinion it is not a problem of the host

Hi,

What version of Mibew do you exactly use? And where did your get it?

Also you does not specify the version of PHP you exactly use. The list of PHP versions you've provided contains supported versions but only one of them can be used at the moment.

hi
thanks for answer me
MIBEW: 2.0 beta.5
Super Ultra Extra specific info php  : ATTACHMENT

[Dmitriy Simushev]

Once again. Where did you get Mibew?

[manhast]

ops sorry
this: https://mibew.org/announcements/2015/03/30/mibew-messenger-2-0-0-beta-5-has-been-released
and I tried on 5.4 php, same situation

[Dmitriy Simushev]

Well, if you've got Mibew from the GitHub repository you should install composer's dependencies before install Mibew. If you've got Mibew from SourceForge make sure vendor/symfony/yaml/Symfony/Component/Yaml/Parser.php file exists.

I created another account and I downloaded Mibew latest version but nothing to do , error persists
I tried to run on wamp , same situation ( screenshot).
you Mibew v2.0 will work? how did you do ?
which host you and which version ?
and how do I install composer ?

[Dmitriy Simushev]

As I've told you before there are two ways to get Mibew:
  1. From the GitHub
  2. From the SourceForge

The first way (using GitHub) is only for developers who knows what Composer is and how it works. Frankly, it's not a sacred knowledge and the docs can be easily googled. Thus if you really want to use this way just RTFM: https://getcomposer.org/doc/00-intro.md. Please, don't ask questions about Composer, Gulp and other third-party stuff here or you will be banned.

If you are not a developer or just can't use our GitHub repository then download pre-built Mibew from SourceForge. Here is the link: http://sourceforge.net/projects/mibew/. There is a readme file inside the package that describes installation process well. I STRONGLY RECOMMEND you to use this way. And yes, this way does really work. The result is https://demo2.mibew.org/.

hi sorry for delay of answer.
the ways you suggest not working for me, i have a question: what's host very compatible on mibew 2.0 beta 5
thanks for help

[Dmitriy Simushev]

the ways you suggest not working for me

It means that you do something wrong. I have no telepathic abilities so I cannot really say what exactly in your actions is wrong.

i have a question: what's host very compatible on mibew 2.0 beta 5

I cannot suggest any suitable third-party hosting because I don't use them. All system requirements are listed in the README file that shipped with Mibew. Let me quote it for you:

REQUIREMENTS

 * Apache web server 1.3.34 or above with the ability to use local .htaccess
   files (mod_rewrite module is optional, but recommended)
 * MySQL database 5.0 or above
 * PHP 5.3.3 or above with PDO, pdo_mysql and gd extensions

the host altervista is free and have many limits, i find other host free "hostinger" it's working mibew 2.0.
i thinks the problem is hosting.
