Incorrect format parameter

Reason: You are getting this error because size of your filename.sql is greater than maximum upload limit. (By default you can import upto Max:2,048KiB)

Solution:

1. Navigate to xampp\php\php.ini
2. Find upload_max_filesize and increase it to desired upload side (e.g. upload_max_filesize=128M) and save
3. Restart xampp

Find php.ini in the xampp

• 1- post_max_size: 128M (give a size for example 128)
• 2- upload_max_filesize : 64M (for example 64)

post_max_size must be larger than upload_max_filesize to fix the problem.

Adding solution as a answer text so that the question drops from the Unanswered Questions list. Original answer is provided by the question author in a reply/comment on his original question text:

I uninstalled both 1.7.1 and 5.6.3 and then re-installed 5.6.3. That did the trick.

In my case this worked:

1. logout
2. clear url (remove all after ?, wspecially token=blablabla must be removed)
3. remove all cookies
4. refresh
5. login

This can't fix the problem basically as the same error may appear in any time
