Hi everyone;
I need to attach any file to an item in k2;
all of file types are OK, but when i attach a mp4 file, it's not uploaded and in database i have an empty record!

Best Regards

Are you sure you are not using any security extensions that might block that file, and/or is that file smaller than your upload limit?

No, I`m not using any security extensions;
I can upload any mp4 file from default media manager of joomla and I can upload mp4 in PhocaDownload too but, in K2 Attachments i can`t upload any mp4 file. when i click on publish button i don`s see any error and in table of attachments in database i have a empty record.

Are you using a UTF filename or Arabic?

Furthermore which version of Joomla! and K2 are you using?

I used UTF filename like parande.mp4
my joomla version: 2.5.20
and my k2 version: 2.6.5

can i replace the files of attachments part of k2?

Can you try with Joomla! 2.5.22 and K2 2.6.8 please?

Problem solved with Joomla! 2.5.22 and K2 2.6.8 ! :woohoo:
Thank you very much!

You 're welcome :)
