I have different fields and showing in different blocks, and want to apply exposed filter to all but my problem is it shows different exposed filters for each different block. I want to make it common for each block.
Below are the steps,
- I made 5 blocks to be displayed for each buttons.
- Added exposed filter for languages for each block.
Now each block showing its different exposed filter. But I want the exposed filter should be shown above the buttons and should work for each block display. Attached screenshot for the issue.

I installed Views Global Filter but is gives Session error.
I was just about to suggest the Views Global Filter.
Another way is to set a contextual filter on all your blocks that pulls from the url, so they each pull the same value. This is an active issue in the views issue queue, with a few people who have made it work: https://www.drupal.org/node/1587894 Comment #6 has some simple code, and that would be applied here https://www.drupal.org/node/1871388
