Here is a collection of common issues that I get report of via email, with instructions about troubleshooting them. Please note that most of these problems are not directly related to iCleaner, though I will still try to address them.

General rules of thumb:

Most problems with the iCleaner app itself can be solved by reinstalling it. Please make sure you're installing it from one of my official repositories, from the BigBoss repo or from Karen's repo. Cracked iCleaner packages can cause all sorts of issues, which I won't be giving support for.

Most seemingly iCleaner-related side effects (including, but not limited to: safe mode crashes, user interface glitches, screaming children haunting your dreams, etc.) can be solved by respringing, or rebooting your device.

If restarting your device didn't work, try disabling all tweaks or your tweak injection library altogether. If your problem goes away, then iCleaner is not the cause of your issue. You may have installed a faulty or incompatible tweak, and it's up to you to track which one is causing your problem and uninstall it. You can use iCleaner Pro's Tweaks tool to easily identify which tweak is the culprit.

I cannot find iCleaner on your repo, or it is completely empty.

This may happen if you also have Karen's repository, which also hosts my packages. If that's the case, you can just download iCleaner from there.

It may also happen due to pirate repositories hosting iCleaner packages that shadow my own packages, in which case: remove all your pirate repositories and the official packages will pop right back.

The iCleaner app crashes.

Oops, there might be a nasty bug somewhere in my code. Unfortunately, sending me an email complaining about it won't help much in determining what is making it crash. You're much more likely to see the crash fixed if you do the following:

• Install CrashReporter or Cr4shed, open it, navigate to the latest iCleaner crash log (they're ordered by date and time), and grab both the crash log and syslog.
• (optional) Make a short video showing me when exactly the app is crashing. This will help me understand what may be causing it.
• Compose an email explaining what's happening, and detailing the steps to reproduce the crash. Important: make sure to specify your device, iOS version and iCleaner app version.
• Attach the crash log, syslog and the video you made, then send all of this to [email protected].

Thank you, and sorry for the trouble!

I installed iCleaner, but its icon isn't showing up.
iCleaner's icon or other SpringBoard icons disappeared, or are completely white.
iCleaner or other jailbreak apps crash upon startup.

This issue is usually caused by icons cache being uncorrectly rebuilt and/or a bad applications state, which may be caused by misbehaving tweaks. It may happen randomly after installing apps, tweaks, applying themes and generally pretty much anything that requires a respring. You can try several things to fix it:

• Reboot, or hard-reboot your device.
• Run iCleaner again with "cache files" enabled, then let it respring.
• Open up any terminal emulator and run "uicache" (without quotes), then respring or reboot your device.
• Reinstall your tweak injection library. Make sure to select "reinstall", don't remove it or all your tweaks will be uninstalled as well.
• Reinstall the affected apps/tweaks.
• Reset your home screen layout ("Settings - General - Reset - Reset home screen layout").
• (iOS 6 and earlier) Install "SBSettings" and use the "fix blanks" function. Just open the SBSettings window, tap on "More", then "Dock Applications" and finally "Fix Blanks" in the upper right corner.

If none of these solutions works, you can try forcing the applications state to be rebuilt. To do so, backup and delete the following two files:

/var/mobile/Library/Caches/com.apple.mobile.installation.plist (iOS 8 and newer firmwares don't have this file)
/var/mobile/Library/Caches/com.apple.LaunchServices-###.csstore ('###' is a three digit number)

Then reboot your device. After you unlock it, your apps should start to slowly pop back up on the home screen.

When I try to "buy iCleaner" or "manage registered devices", an error pops up saying the server is unreachable.

This issue is usually caused by cracked iCleaner packages, which disable the ability of the app to contact the registration server. You may have updated to a cracked package by mistake, or may have intentionally installed it. Either way, the fix is uninstalling iCleaner, and reinstalling from one of my official repositories or from the BigBoss repo.

If this is not the case, the registration server may actually be offline. I'll probably be already working on it, though if you keep displaying this error, feel free to send me a support email via the app.

I purchased iCleaner, but my device is not yet registered or I didn't receive my registration code.

Purchases are usually processed instantly, but they may be delayed by Paypal for various reasons. If you did not receive your registration code within two hours from the purchase, feel free to drop me an email at [email protected].

I deleted my language by mistake, how can I recover it?

If you enabled "test mode" beforehand (as recommended), just use the "restore backup files" function. Otherwise, you will have to restore your device.

One of my applications is broken or not behaving as it should, or it's missing some save/update data.

Some applications may store useful information in their cache folders (yuck!), which are being deleted by iCleaner. This can result in the app not behaving correctly, or missing some data. Some apps are tolerant, and will just re-download the needed files upon startup. Other apps will have to be uninstalled and installed back.

After doing this, you can exclude the app via the "Excluded apps" submenu in iCleaner. This will prevent iCleaner from cleaning up that specific application. Note that, as of version 7.2.0, iCleaner features multiple app exclusion menus, one for every relevant removal tool.

Finally, "Test Mode" is your friend! You can always make a test cleanup when you install new applications, and eventually restore the backup files if you notice any problem with them.

Some applications are displayed in a quarter of the screen.

This is caused by some tweaks that are incompatible with your iOS version. As always, iCleaner Pro's Tweak tool can help you pinpoint the culprit.
