Before you do anything else, make sure that your server complies with the minimum requirements of Akeeba Backup. The PHP and Joomla! / WordPress compatibility matrix is published on our site.
If your environment does meet these requirements, please go through the client-side troubleshooting. 90% of interface issues are attributed to PC configuration. You must go through that list before proceeding.
FIrst you need to locate your media files directories. It depends on which edition of our backup software you are using:
Akeeba Backup for Joomla!: the directory
media/com_akeeba under your site's
Akeeba Backup for WordPress: the directory
under your site's root
Akeeba Solo: the directory called
under your Akeeba Solo installation
If you are on a commercial host running Linux or a local server running on Linux or Mac OS X, the first thing you have to do is to try and give the media files directories and all of their subdirectories 0755 permissions. Give the files inside these directories and all of their subdirectories 0644 permissions.
If you are on a local server running on Windows, you have to do a slightly different procedure based on your Windows version.
If you are on a Windows XP Home machine, use Windows explorer to find the media files directories. Right click on it, select Properties and clear (unselect - it must be blank, not gray!) the Read Only checkbox. Click OK and, if prompted, tell Windows to apply this to all files and subdirectories.
If you are on a Windows XP Professional, Vista, 7, 8 or 10 machine, use Windows explorer to find the media files directories. Right click on it, select Properties and click on the Security tab. If you do not see the Security tab you have to go to Windows Explorer (i.e. open any folder) and click on View. Uncheck the Use Simple File Sharing option. You will now see the Security tab. In the Security tab click on the Edit... button. If you can't see a user named Everyone, you will have to click on the Add... button, type Everyone in the big text box and click OK. Now click on the Everyone user and then take a look at the list of checkboxes below. Click the Accept checkbox on the Full Control row (the topmost one). Click on OK, then again on OK. Repeat that for every media files directory., ,
If you are on Windows and the previous solutions didn't work for you, you will have to use the command line. Open a command prompt and go into the media files directories of your site. Now run the following two commands:
attrib -s -h /s /d attrib -r /s /d
Repeat that for every media files directory.
If this does not help, you have to do some more troubleshooting.
If you are using a CMS (Joomla!, WordPress) most likely you have a plugin in your site which tries to load jQuery without using jQuery's noConflict() mode. We have stopped using jQuery as much as humanly possible in our software since March 2017. There are a few places where this is still used. In case there's a jQuery conflict you have to contact the author of that plugin and explain to him that what he is doing is causing conflicts with other software. We use noConflict() in our code to make sure that we don't cause conflicts on our end, but we can't guarantee that third party developers take equally prudent measures with their code.
You may also want to check that the media files directories really exist and contain all of the files we ship with our software. If any of the directories or files is missing then you have an incomplete installation of our software and you need to reinstall it. If you are on Joomla! you must follow our installation troubleshooting advice in order to reinstall Akeeba Backup successfully.
Finally, you may have some .htaccess directive which disallows access to those files. Try renaming your .htaccess files to .htaccess.bak. Remember that .htaccess files are inherited based on filesystem order. It is possible that a .htaccess on your main site is inherited by a site in a subdomain if the subdomain's root is inside your main site's root. If renaming all .htaccess files allows our software to load, you have to figure out which of the directives you put inside your .htaccess file is causing this issue.
