rc1 to rc2 upgrade problems

I'm having the same problem. Here's the error message that's showing up in my logs:

PHP Fatal error: Class 'views_plugin_argument_validate' not found in /*****/*****/public_html/sites/all/modules/views/modules/taxonomy/views_plugin_argument_validate_taxonomy_term.inc on line 11

I had upgraded from to 6.x-2.0-rc2 from views-6.x-2.0-beta3

Thanks

Same thing on my site. Spent a couple of hours trying to figure out what happened before I reverted views to rc1. So, yeah, this a MAJOR problem.

My guess from searching through the code is the addition of the function:

/**
 * Get a list of modules that support the current views API.
 */
function views_get_module_apis() {
  static $cache = NULL;
  if (!isset($cache)) {
    $cache = array();
    foreach (module_implements('views_api') as $module) {
      $function = $module . '_views_api';
      $info = $function();
      if (isset($info['api']) && $info['api'] == 2.000) {
        if (!isset($info['path'])) {
          $info['path'] = drupal_get_path('module', $module);
        }
        $cache[$module] = $info;
      }
    }
  }

In the new version as the newest version of OG doesn't implement this function. I will go and post this bug in the OG project.

Upgrade OG to the HEAD version, it fixes the issue.

I tried to upgrade from rc1 to rc2 in a usual way, i.e. I removed views folder and upload rc2 in its place. But I simply can’t submit modules page. I only managed to do this if views rc1 is completely uninstalled before upgrade. But how can it be done on live sites with working views?

The problem reported in the original issue is fixed in -dev.
