Warning while playing audio

Sermon Speaker seems to call another plugin script.

Warning: Missing argument 4 for plgContentSimplepictureslideshow::onContentPrepare() in /home2/hisglor4/public_html/plugins/content/simplepictureslideshow/simplepictureslideshow.php on line 20

Warning: Missing argument 4 for plgContentSimplepictureslideshow::onContentPrepare() in /home2/hisglor4/public_html/plugins/content/simplepictureslideshow/simplepictureslideshow.php on line 20

SermonSpeaker processes the content plugins for the scripture and the notes field.

This warning is likely created by the Content Plugin "Simplepictureslideshow". It seems to expecting a fourth parameter (page) which should be an optional parameter ($page = 0).
You can try to deactivate said plugin and see if it solves the issue.
You can also contact its developer and ask if they know how to fix it.

You could of course also just deactivate PHP warnings

The next release of SermonSpeaker will have a small change in how it's calling those plugins. Maybe this will fix it as well, not sure thought.

Thanks for your response. I used a plugin called simple slide show for displaying photos. Why does Sermon Speaker call the plugin at all?

Because of the way Joomla handles the plugins

Joomla has some defined events like "onContentPrepare" which fires all plugins who are registered for this event. So if this event happens, every content plugin gets called and every content plugin will check the $text if it has anything to do.
Since SermonSpeaker supports content plugins in the notes and scripture fields, we call these event as well and thus Joomla calls each content plugin.

Thanks.

I used both sermon speaker and simple slide show in Joomla 1.5. And I found no problem at all. So far, to turn off the warning is the best way for me.

I just verified - it will be fixed with SermonSpeaker 4.1 as I use another way of calling Plugins there.

If you want to fix it in the plugin, you could change the file found in:

/plugins/content/simplepictureslideshow/simplepictureslideshow.php

Change the line #20 where it says: to and it should be fixed.
