Moving Codigniter from windows server to Linux based server

Question

I have moved a CodeIgniter based site from a Windows based server to a Linux based server. I have had various issues. Currently I am stuck on images failing to upload. (server timeout error)

Steps taken: Set uploads folder to 777. Try php 5.4 & 5.2. I was looking for a suspected temp folder somewhere, but not finding one. I have searched, and found an article discussing CodeIgniter timing out after 300s. But in my case, it times out almost immediately upload is initiated. File attempting to upload is 41kb. I have checked php settings, max_input_time: 60, upload_max_filesize: 64M, post_max_size: 64M Not sure what else I can add.

After more searching, and some tests, it is more than likely a conflict between Ajax and CI. A normal php upload works. I found a few articles discussing issues with CI and Ajax. Unfortunately, they dont seem to match my code.

And more: I found some log files. They do correspond to what I did on the website. The first line is the last line displaying action of refreshing web page and time taken. The following lines are for click on browse for image and click upload. Interesting is a couple of ignored attempts to load files.

More Info: 11 Jun 2015:

After much searching, I think this is not a CodeIgniter Issue. It appears to be an issue with Dojo. I found this within the product.php file

if (!$this->ajaxupload->do_upload('flashUploadFiles'))

Somewhere in this file there should be settings for Dojo, but I cannot find them. Dont know what I am looking for really. The help on the Dojo website seems really confusing. I also supect that there is more than just upload the Dojo files and put some code in the correct place to activate it. I wonder if there is something that has to be activated on the server.

I have also added Dojo to the Tags List

Answer 1

The error may be related to permission, just follow the steps, these may help you

1. check you base_url in config.php file and other path for uplaoding (if given).
2. Check that all images and assets used in codeigniter are with project folder, not anywehere else in your computer.
3. You should have a folder in root of your project named like assets, and its permission should be 777 hiearchically for all folders and files.
4. Permission for 'application' and 'system' folder should be 755 also for all folders within it, and for all files in it , permission should be 644.
5. if problem not solved, check images path, may be it is refering to any location to you computer, if path statically bee used. you should manage this.
6. If your url got changed, change it also in .htacces file.

Answer 2

I had a Freelancer work on this for me, It turned out to be a Session timeout set too short.

Thanks for all who took the time to answer or read.
