Beta testers needed for EventCalendar v1.2

[apkoutsou]

As the changes are thorough, I decided to release to the Elxis Community a beta version of EventCalendar for testing and bug digging.

There are some known issues, that I certainly need help to deal with:
* Either my local installation or a live Elxis site were able to send the invitations using the mosMail function.
FIXED: A bug had eaten an 'e' in front of the 'mail' variable, so an empty string was passed to the recipient argument of mosMail() function!
* On a live Elxis site the syndication option raises an error, as for an inexplicable reason the rss function adds blank lines before writting the RSS xml code. That didn't happen on my local installation.
FIXED: Some empty lines were found the end of a php file, that passed at the rss xml file!
* I have been trying to use the IPN notify feature of PayPal (using a sandbox account) but even though the transaction is done, I always get an error response form PayPal, so the event reservation system can never verify the reservation.
PENDING: Still needs to be checked...
* When I use the Tabulator while in admin area and in the same pane I add two TinyMCE (using the editorArea() method), the second TinyMCE seems to be disabled (with no cursor and no text displayed), but if I click on it and press any keys, they are inputted to the text area, but not to the TinyMCE. Does anyone know why this mihgt be happeining?
PENDING: Still needs to be checked...
* There are some fatal PHP errors when displaying the weekly calendar due to wrong usage of the strtotime function, but I'm going to fix them.
FIXED: Five (5) more bugs found and I do not get any errors!

Nevertheless, the code needs a lot of optimisation (memory usage, duplicate code et.c.) yet to be done, so there may be more bugs that I haven't yet discovered.

You may find the beta version here.

I would appriciate if anyone could post some suggetions over the above mentioned problems. I have not yet found any solution nd these are the last things I have to fix before the release...

I have fixed most of the bugs except the PayPal functionality. Have anyone tried it and worked?

[apkoutsou]

I am really stuck. I am using this class for the PayPal integration, but I cannot make it work with PayPal Sanbox.

This is the last call, if no one can help me I'll have remove the two pending features...
