Recently comments posted to my website have all been blank, including my own, despite having message content in them. The comments get posted and show up, but their content is blank. Checking the error log, the time indexes correspond to this error:
PHP Warning: call_user_func_array() [<a href='function.call-user-func-array'>function.call-user-func-array</a>]: First argument is expected to be a valid callback, 'wp_target_blank' was given in /home4/tropicg9/public_html/blog/wp-includes/plugin.php on line 170
Looking at line 170 and the last bit of preceding code in the specified file "plugin.php", this is what is there:
Line 170 is the last one. I'm at a loss as to how to deal with this error. Disabling all plugins did not fix it. This seemed to happen shortly after upgrading from 3.3.1 to 3.3.2. Any help would be appreciated.
[No bumping, thank you.]
