Steps to reproduce the behavior

Go to http://127.0.0.1/ak/mibew/install.php in a clean build

1. You didn't specified the version of Mibew Messenger.
2. How have you got Mibew to install? Has it been downloaded from our official site, or have you built it youself?

[Akiracr]

Hi @faf, sorry for the missing information.

I clone master and built it myself as result of it was mibew-3.5.7.zip, I've download a zip from the official site and compared them with my build and it is practically are equals, so i've tested that version and the result are the same deprecated messages.

Please tell me if you need more information or if there is something that i can do to help to solve the problem.

[faf]

@Akiracr Well, ok, I'll try to reproduce the issue. What Ubuntu distro do you use? And what PHP modules are installed (you could just post the output of php -m command).

At the moment I could only guess that the last fatal error probably means that you hadn't properly set database connection options in the configuration.

[Akiracr]

I'm running it on a docker php:8.1-apache container, i've reviewed an it is Debian 11 (bullseye), the result of "php -m" is

My database config settings seems to be ok, it can't connect to the database but /install redirects to /operator/login, here is the complete output when try to access to /install

So, to sum it up, the problem occurs in Debian 11. Right?

[Akiracr]

Yes

[faf]

Ok. I've set up the clear system with Debian 11.

To begin with your installation is definetely is not the standard Debian 11. Since Debian 11 comes with PHP 7.4. Though, it's not a big deal to set PHP 8.1 there.

Then. Your problem consists of two parts.

1. Deprecation warnings.
2. Fatal error.

I was able to reproduce the first part. I was able to (partly) reproduce the second part. I was unable to reproduce the whole issue in the way you've described.

Deprecation warnings comes from the Symfony framework. I have some ideas on how to get rid of them, but at the moment I'm unable to say when that will happen. Right now the most simple way is to hide that warnings by either disabling the display_errors option in mod_php config, or at least set the error_reporting to recommended production value of E_ALL & ~E_DEPRECATED & ~E_STRICT.

As of fatal error... Frankly, no idea. I'm unable to reproduce it.

1. Double check your database connection settings in config.yml. Does your database exists? Does your database user has permissions to access and manage the database?
2. Do you have mod_rewrite enabled and AllowOverride All option set in the configuration of Apache2?

Hi @faf, thanks for your time and comments, i has been testing and found that mibew is not compatible with PHP 8.0 and 8.1, on PHP 7.4 works without problems and warnings.

It cound be because some symfony dependencies are so old and are under unmaintain status.

I'll try to work on it.

[faf]

i has been testing and found that mibew is not compatible with PHP 8.0 and 8.1, on PHP 7.4 works without problems and warnings.

That's not true. Mibew Messenger is compatible with PHP 8.1 since v3.4.3. For example, our demo installation works on PHP 8.1.

Warnings on deprecated features (that comes from some Symfony components as well as from some parts of Mibew itself) doesn't mean that the code is not functional. It will become not functional with future versions of PHP, but at the moment the code works.

[Akiracr]

Umm, could you test the installation on PHP 8.1 recently?

My environments of php 8.1, 8.0 and 7.4 are indical about OS, Apache, and php extensions, but in PHP 8.0 and 8.1 gets fatal error. Maybe there are some problem only with the instalation process.

[faf]

Yes, it was tested on clean Debian 11 system (with attached deb.sury.org repo to get PHP 8.1). Both install and main functionality works fine except for deprecation warnings when standard PHP settings altered to produce most verbose output.
