Which captcha plugin are you using? Is this plugin - AND the version you have installed - compatible with Elgg 2? What exactly "does not work"? Is the captcha input not displayed on the registration page (or whereever you expect it) or is it shown and the submit of the form with captcha input does not work? Has it worked before - if yes which version of Elgg and which version of the plugin?

I am under elgg 2.3

Now you have posted only which plugin you use but not answered any of my other questions.

The Captcha plugin of mine in version 2.3.0 should definitely work on Elgg 2.3.

If you have updated from an older version of the Captcha plugin without completely replacing the captcha plugin folder (just copy the new version over the old version) it might cause the problem. So, deactivate the Captcha plugin, then delete the captcha plugin folder. Only then copy the new version to the server again and activate the plugin again.

If it still doesn't work, deactivate ALL other 3rd party plugins you have installed. Only keep the Captcha plugin enabled. Does it work now? If yes, one of the other 3rd party plugins you use causes the problem (either this plugin is not compatible with Elgg 2.3 or not correctly installed). You can find out with plugin it is by activating the plugins again one at a time.

If the Captcha still doesn't work with all other 3rd party plugins disabled, I'm at a loss what could be the reason for the problem.

i can't find were to setup the cron job to call ffmpeg and how to configure it.

Thanks Nikolai

i am trying to figure out whats wrong as i see the code of the init of the cron in the IzapVideoBootstrap.

Thanks for your explanation in the discussion, its pretty clear

The cronjob you need to set up is not a cronjobs specifically to iZAP Videos. The iZAP Videos plugin hooks into the cronjobs you need to add for Elgg itself fully working. The Elgg cronjobs (if configured on a server) triggers the execution of the functions hooked into the corresponding time intervals. As long the cronjobs of Elgg are executed at their corrresponding interval it's no further work necessary. The iZAP Videos plugin allows to select the time interval to be used if you want to use a specific interval or can't add all Elgg cronjobs and/or don't want to use the 1 minute intervall for triggering the video conversion.

How to add the cronjobs of Elgg depends on your server scenario. If you have CPanel to administrate your server, you can add the cronjobs there. Have you already tried to add the Elgg cronjobs? If not, please try and if you have trouble, ask again and provide some more details about your server setup to help us to help you.

Beside the cronjob issue you also need to get all errors shown on the Server Analysis tab of iZAP Videos fixed. The exec() command must work. Also, php and ffmpeg are not found on your server. In the latter two cases you might just need to provide the correct path to the php and ffmpeg executables on your server on the iZAP Videos plugin settings page. If the php and ffmpeg errors are gone, the exec() error might be solved, too. If not, the usage of the exec() function of php might not be allowed on your server (disabled on the php.ini of your server).

Only if there are no errors on the analysis tab and the cronjob (the one interval used by iZAP Videos at least) has been added, you can expect the conversion to work.

There are many server scenarios possible. Therefore, it's simply impossible to give you any guidance or provide you with a tutorial of how to set up a VPS that would be specific enough for your situation. I can only suggest that you try to find a suitable guide/instruction by doing a Google search. Doesn't your webhoster provide support? Ask them first. I would expect a hosting plan contains at least a pre-configured VPS with the typical services (LAMP stack) already working. If you have not much experience in server administration you might choose a webhoster that offers the necessary support. This is unlikely to be the cheapest host but that's how it is.

Installing Elgg is the step following the setup of the VPS, i.e. as long as your VPS is not fully working and fulfils the requirements of Elgg there's no point of installing Elgg.

Thank You iionly!
