   This error has only started in the last few days. Everything worked perfectly up until then. As far as I know nothing has changed, this is why I am confused.

   When I go to upload images (already compressed to 800x600) I get a failure notice BUT the images are actually uploaded and the thumbnails are created. I don't know why I get the failure notice though. The site is a clients site so having failure notices appearing is obviously not ideal.

   So any idea what is going on here?

   Thanks!

   My server stats are
   

   * Operating System : Linux
       * Server : Apache/2.2.3 (CentOS)

   I am having the same problem, is it a server configuration problem as it worked fine on the old server I just brought it over from, but can not figure out what it could be!

   Any help would be great.

   Narrowed it down to it not being able to create a thumbnail, the larger image is there, all folders have correct permissions.

   All seems to be good.

   If anyone can help, here is a link to my phpinfo()

   I had this problem when developing with

   • Wordpress MU 2.8.4
   • using NextGen Gallery 1.3.5.

   The problem was occuring due to some extra invisible characters being tacked on to the msg variable in the run function of the ngg.ajax.js file.

   To make this work properly, I added parseInt to the switch statement parameter like so...

   Approximately Line 30 of ngg.ajax.js

   
success: function(msg){
switch (parseInt(msg)) {
case -1:

   ....

   Don't forget to remove the double quotes from the case statements!


   If this fix worked for you, please let me know.
   I know it drove me nutz.

   i changed the code (as suggested above) and i'm still getting the same "A failure occured" error messages.

   Can't seem to upload more than 40 or so images into a single gallery without this error popping up.

   love this plugin, but this error is really hurting its effectiveness atm.

   thanks for any help, in advance

   Hi boilr,

   When you click on the [more] link, does it show up as '1'?

   @ shawnkltucker:

   no "1" - instead i get:

   [more]
   [object XMLHttpRequest]

   when i mouseover [more] that is what shows up. nothing actually clicks thru

   strange cause i never had any issues until the latest release. not sure if its NGG and/or some issue with 2.8.4

   I am seeing similar issues on some but not most images I try to upload.

   I originally thought it was because images I was trying to upload were very large, but my upload_max_filesize PHP setting is 100M, so that couldn't be it, right? Or since I'm working with Flash, does it have its own built-in filesize limit?

    Hi boilr,

    My fix is for a separate issue.

    Going on stevemagruder's comment, try adjusting you php memory limit.
    In general, the memory limit should at least be twice the size of the max upload file size.

    Also strange things happen when scripts time out. Try adjusting the max execution time in your php.ini. I think the default is 30 seconds, so try pumping it up to 120 seconds.

    Please let me know if it works.

    I having this problem as well.

    The javascript fix doesn't seem to help. I have pumped the memory limit and timeout numbers on the PHP side (even though no error is being reported in the server logs). I've tried multiple browsers, multiple versions. I've deactivated every plugin on the site except for this one. I've uninstalled and reinstalled the plugin.

    Would love to see a real solution to this, if someone has one.

    I'm also having this issue. its driving me insane. The images upload fine, but when it tries to create the thumbnail i get "an error has occured" with no explanation.

    I'd like to try shawnkltucker's fix, but im not sure where to add this code. if this help here is my server info....

    * Operating System : Linux
    * Server : Apache
    * Memory usage : 11.61 MByte

    Hi,
    my ngg.js does not show any line with function(msg) so where should I put it? (You mean the ngg.js in the plugin/nextgen-gallery/js/ directory, don't you?)

    (my German Server-stats, although it really sounds like a msg-problem, as thumbnails are created correctly, and it just gives the error-explanition "1" when I click on "more"..

    Sorry... the file was plugin/nextgen-gallery/admin/js/ngg.ajax.js

    But I still have the problem, the file looks like this on these lines now:

    success: function(msg){
    			   		switch (parseInt(msg)) {
    			   			case -1:
    					   		nggProgressBar.addNote( nggAjax.settings.permission );
    						break;
    			   			case "0":
    					   		nggProgressBar.addNote( nggAjax.settings.error );

    Why do I remove the doubledashes for the -1 statement for case?

    A client of mine is receiving the same error as boilr.

    [more]
    [object XMLHttpRequest]

    Happens each time he tries to upload a new image. What's strange is that when I try I don't receive the error. He's on a Mac, I'm on a PC. Would that make a difference? I also noticed that the images upload but the thumbnails are missing.

    I'm at a lost as to what to do.

    Odd that the error appears only for some.
    Could be a browser compatability issue.
    Since javascript is implemented differently in different browsers, and Ajax uses java script to function.

    For those of you that receive the error, what browser version and OS are you using?

    I have successfully used IE8 and Firefox 3.5

    Google Chrome 3.0.195 and Firefox (although I don't know the version here) have produced the error for me and a colleague using it on his computer..

    I have the same issue. I have several images in a gallery and they display fine. It's only the thumbnails that are not being generated.

    When I manage a gallery, I can select an image and set the action to generate thumbnail. The ID 4 error then occurs and no thumb is generated. I don't think it's a browser issue as I've seen it in Chrome, Firefox, Flock and IE (all latest versions).

    It appears to be a server problem.

    I have installed the exact same NextGEN Files on another server, but don't get the error there.. it must be a server error, but how can I fix it?

    I had similar errors like many. I am new to WP/NextGen. I installed WP 2.8.4 and NextGen 1.3.5. When I created galleries (imported images), the thumbnails would get created correctly BUT I will always get an error for each thumbnail with a ID and text saying "a failure occurred" and more below. Mouse over more would show character 1. Shawnkltucker's solution which Alex said was a good change, solved my problem. Initially though I thought it did not solve because I kept seeing the same issue. However one day later the problem was indeed solved. Looks like we ALSO need to clear browser cache. I used Firefox 3.0.6 on XP-SP3. Before trying Shawkltucker's suggestion I had tried increasing PHP memory to 96MB - no luck. My images are between 50K and 150K. I even took packet captures and the packet captures showed response to the Ajax call returning just a Hex byte 31. Still Shawnkltucker's suggestion has worked for me.

    To Llase: You must remove the "" from all the case statements.

    I have two more problems to fix - cannot edit thumbnails. And cannot see alt/description text when I mouse over slideshows.

    Thanks Alex for a nice plugin.
