[ColdWabmaster]

Hello,
      I considered some paid ad posting for our users. But the payment plugin is showing warning message in the entered paypal API credentials that means API Username, Password and signature are replaced by following warning messages and it changes everytime I re-enter. Please note the sample Warning messages.

I reinstalled the plugin and now its working fine. I don't know why after updates some plugins throws off errors...is it because of the settings>General>Software Updates .... what should I set the Core Updates to ...? and should I check the remaining checkboxes...?

[design]

yes, it should be suggested to turn off plugins and perhaps permalinks. I think the 3.2 upgraded with the permalinks turned on screwed up a lot of sites.  anyhow, glad your back up and running.
