Admin Tools has detected that some of its files are missing or have been tampered with. Most likely this is caused by a Joomla! bug which causes some files to not be copied on component update. You are advised to install the component ZIP package twice, without uninstalling it before or in between installations.
If you want to see a list of the files and directories which are missing or tampered with please click the “Run files check” button below. If you want to ignore this message and continue using Admin Tools you can click the “Ignore this message at your own risk (NO SUPPORT)” button but in this case be advised that your Admin Tools installation will not work properly and we will not provide support.
