Page not found

Try to deactivate and activate the plugin. May be something wrong with links settings.

Also here is most possibly conflict with your current theme/other plugins.

Try to deactivate/switch them and see when issue will be solved.

sorry for the delayed reply

i’ve deactivate and activate the plugin.
I’ve change the theme to the simplest theme. Twenty fourteen(basic WP theme)

Still the same error occur.

any advise?

to add up to it,
I cant even edit your ssample test upon download (the Eysenck’s Personality Inventory (EPI)test).

I edit some marks, uppdate and i receive the page notfound error,
This time, with new installation

Something is wrong with your link.

I’ve reinstall the whole wordpress.

With fresh installation, this time, when i want to update the test, it jumps from Tests area to Posts area.

please look into it.

Which other plugins do you have enabled?

none other than wp-testing

@ezwanzamzuary, not confirmed. I can edit and update tests by credentials which you provide.

Show us screenshots what you do and what you get.

any updates?

Research your server settings. some extension like suhosin or it’s too restrictive settings could be the reason.

Locally I can not reproduce what I see on your server. So it’s clearly server settings issue.
