If you try to open your Synology phpMyAdmin Package and encounter a blank page with just an error text saying “No input file specified.”, know that it is an error due to Permissions for your phpMyAdmin folder. I am sure that you too might be scared, just like I was, but rest assured that everything can be resolved in a few simple steps.
First of all, to fix this, right click on the phpMyAdmin folder, then click on Properties. Follow the instructions in the image below.
At times, after having installed a new version of phpMyAdmin, it can lose Permissions. All you have to do is give back the appropriate Permissions to the “SYSTEM” (Read and Write) to make the error disappear forever. Remember that the error could happen again every time you manually update phpMyAdmin, but now you know the solution. So, to make it clear, go to the phpMyAdmin folder that you will find on the web / phpMyAdmin and right click on it, then click on Properties. Then go to Permission/Create and type “SYSTEM”; this way you give the SYSTEM permission to Read and Write and save the settings. Sometimes you have to add Permissions to admin too, but only if you encounter this problem. Follow the instructions in the image below.
Hopefully, you will not have to deal with this problem again. If you have any questions, do not hesitate to contact me using the specific page.
