Upload failure reason unknownX -> unable to upload images for the ads

[legtech]

Dear Forum Members,

I am running a website with OS Class 3.6.1 and Bender Black theme (3.1.3), today I tried to add some ads to the website and when I got to the part where I am supposed to upload pictures it gives an error "Upload failure reason UnknownX".

I have looked thru the previous posts on this problems, I would like to note that I have tried disabling and enabling Image Magick / GD - did not solve the issue.
I checked the permissions for the uploads folder - 755.

If someone could guide me on what to do next and where to look I would immensely appreciate it!

Thank you in advance for your time and attention! I truly appreciate all the support I get here.

Hi,

That happened suddenly? Were you able to upload images before? If so, have you changed anything recently (some new plugin, theme modifications...)?

Ebable debug to see if there are PHP errors:

The Debug Log shows the following:

Stack trace:
#0 /home/asb/KERWEN/kerwen.tk/oc-includes/osclass/classes/ImageResizer.php(24): ImageResizer->__construct('/home/legtech/K...')

That line 41 (last string) looks like:

40        private function __construct($imagePath) {
41            if(!file_exists($imagePath)) { throw new Exception(sprintf(__("%s does not exist!"), $imagePath)); };
42            if(!is_readable($imagePath)) { throw new Exception(sprintf(__("%s is not readable!"), $imagePath)); };
43            if(filesize($imagePath)==0) { throw new Exception(sprintf(__("%s is corrupt or broken!"), $imagePath)); };

Previously (about a month ago) I uploaded two images as a test. And everything went fine. Then I had some modifications to the plugins - Cars Attributes, Payments Pro. Then I got low disk space issue and resolved it with my hosting provider (there is a forum topic here) having edited the php ini file.

The full Debug message is below:

[11-Apr-2016 17:50:30 Asia/Tashkent] PHP Fatal error:  Uncaught exception 'Exception' with message '/home/asb/KERWEN/kerwen.tk/oc-content/uploads/temp/qqfile_570b9d9640143.jpeg does not exist!' in /home/legtech/KERWEN/kerwen.tk/oc-includes/osclass/classes/ImageResizer.php:41

Check that /home/asb/KERWEN/kerwen.tk/oc-content/uploads/temp has 755 permissions

[legtech]

Permissions for /oc-content/uploads/temp are set at 755

[teseo]

FTP to your site, go to /oc-content/uploads/temp, clean up everything there.

Now login as user on your site, publish an ad, just upload a JPG image. Refresh FTP view and see if there is now a qqfile_xxxxxxxxxxxxxx.jpg. If not so, set permissions to 777 and try again.

Dear teseo,

Did everything as you said:
Emptied uploads/temp folder (btw there was index.php file and 2 images). Permissions set at 755. Same error when uploading pictures on front end.
Changed permissions to 777 - same. In both cases the temp folder remained empty.

[legtech]

In addition to above, the error message changed from previous "Upload failure reason unknown" to "XHR returned response code 500".

[teseo]

Try my plugin Pre-resize Images, it has been reported it has solved those XHR errors

Dear teseo,

I have installed the pre-resize plugin, modified the line in item-post.php (as shown in instructions to the plugin). But the uploading is still not possible. However, now the error shown on front end says that "File is empty". Also, the progress bar (when uploading the image seems to be moving, I mean kilobytes are increasing as if the image is uploading, but at the end it shows an error message.

According to debug log the problem is still with line 41 in ImageResizer.php
uploads/temp is still empty (after I've deleted everything thru FTP)

Sorry I don't know what's happening to you. I can see that you're running PHP 5.6, do you have a way to downgrade to PHP 5.4 provisionally so we might discard that's the issue?

[legtech]

Dear teseo,

I figured out the problem. 

In your first reply you were asking if there were any previous issues with the site, and I told about low disk space I got resolved thru php.ini.
Back then my hosting provider edited my php.ini to switch to PHP 5.6 from 5.4 (payments pro plugin works with at least 5.6). So back then the support team edited the memory_limit as 512M, whereat the file itself interpreted it as 512 bytes and not megabytes. I had figured out the problem myself (with help of GitHub) and edited that line in bytes.

Now, I accidentally checked that file again, and saw that the max_upload_limit was also set to 512M, i.e., same as before, it was interpreted as 512 bytes! So, I just entered the value in bytes.

As of now the images are being uploaded smoothly. I can't believe the solution was so simple, and I could not figure it out.

Anyway, immense thanks for your invaluable time, efforts and support, teseo!

E=mc2. Everything seems simple when you know the answer.

Glad you solved your issue, regards
