@cdorin, this is a rather urgent issue since they want to use the file upload question at a survey starting next week. Can you look into this?

@Mazi, could you check the permissions? Upload folder should be writable by the webserver (known issue by Markus from customers)

@cdorin, good catch. I am not able to upload an image and add it to the question text, so it could be a permission issue causing a misleading error message,

Conclusion: Windows Server is nasty :)

@cdorin, a short update that this was NOT solved by adjusting permissions at server level. That only fixed the issue of not being able to add images e.g. to the question text.

At the mentioned system the file upload question still fails with the latest 3.19.3 version with the error above. The same version works fine at other servers.
@c_schmitz: My guess is that it is related to the PHP version. Is it possible that the recently extended file type extension checks fail with older PHP versions?

Is there any chance someone can test the file upload question with PHP 7.1.x and the latest Limesurvey version? Maybe even at a Windows server?

@DenisChenu, did you ever face such an issue at any customer system?

Strange …

1. User seems to have a valid fileinfo : diablecheck is not set : https://github.com/LimeSurvey/LimeSurvey/blob/1fa5dd4794bab115bd04172258b42e06f123f1dd/application/controllers/UploaderController.php#L187

But his mime seems outdated

See manual : https://manual.limesurvey.org/Optional_settings#Upload_files
Maybe with mime from : https://sourceforge.net/projects/gnuwin32/files/file/5.03/file-5.03-bin.zip/download

See : https://www.php.net/manual/en/function.finfo-open.php#107383

@cdorin, I deleted the attached file since the problem can be reproduced with any file upload question.

Can you please set this ticket to PUBLIC? Again, I am not allowed to do that so sorry for wasting your time.

Please check if this bug still exists in the latest patch release. Thank you.

Hello Mazi,

we have asked for feedback on this issue. Because we did not get an answer we assume that the issue is resolved.
However, should you be able to reproduce the issue using the latest version, please feel free to re-open the issue and give us exact details on how to reproduce it.

Thank you and best regards,

c_schmitz

@c_schmitz / @ollehar: This issue was reported about 1.5 years ago. I do not have access to that system anymore so I can't test. Please test yourself.
