Matt, I have now tested and site function is fine.

However, I am seeing multiple PHP warnings

PHP Warning: Undefined variable $class in .../plugins/sky-login-redirect/includes/options.php on line 698

PHP Warning: Undefined array key "redirect_to" in .../plugins/sky-login-redirect/sky-login-redirect.php on line 281

PHP Warning: Undefined array key "HTTP_REFERER" in .../plugins/sky-login-redirect/sky-login-redirect.php on line 465

Various “undefined” warnings seem to be thrown off a lot with PHP 8 — they don’t impact site function, but they do have a tendency to fill up logs. (I have tried to disable logging of these on my sites, but they still show up in my log, unfortunately)

Alan,
The problem is that warnings can fill up logs on a server pretty quickly. In this case, a single instance generated 8 lines of PHP warnings. 8 lines isn’t much — but if the error is repeated on a moderately busy site over the course of a day, it’s not hard for log files to grow geometrically. I have tried to disable non-fatal error PHP warnings on my server but it just doesn’t work — they keep showing up in the logs.

In my case it doesn’t matter, I can’t run PHP 8.0 on this particular site anyway, so it’s back to PHP 7.4— but I’m going to feel differently next November when active support for PHP 7.4 ends.

And PHP “warnings” ultimately turn into fatal errors as new PHP versions are pushed out. So I simply wanted to let you know because I assume you want to create clean code in the end. I’d think it would be easier to note this now before it becomes a critical problem.

Thank you!

The plugin seems to be functioning ok, but there are hundreds of log entries like this, just over the past month. I am reporting this because I would assume that you would want to write clean code. It seems to be tied to this section of code:

if (isset($queriedObj->taxonomy) && isset($queriedObj->term_id)) {
			/** @since 2.9.1 fix multi-term queries bug */
			$validate = true;
			switch(true){
				case $wp_query->is_category and ($wp_query->is_tag || $wp_query->is_tax):
				case $wp_query->is_tag and ($wp_query->is_category || $wp_query->is_tax):
				case $wp_query->is_tax and ($wp_query->is_category || $wp_query->is_tag):
					$validate = false; //multiple taxonomy queried.
					break;
				case isset($wp_query->tax_query):
					foreach($wp_query->tax_query->queries as $t){
						if(is_array($t['terms']) && count($t['terms'])>1) $validate = false; //multiple terms queried.
					}
					break;
			}
			if(!$validate) return 0;
      $term_id = $queriedObj->term_id;
			$taxonomy = $queriedObj->taxonomy;
			 // debug_msg($wp_query->tax_query->queries, "$taxonomy is ranked $term_id ");
    } else {
      return 0;
    }

Just a follow-up —
I wasn’t able to drop the problem table — the “doesn’t exist” error prevented that as well.

I thought I could export my table, uninstall the plugin and then reinstall it — but it turns out that the export/import features are available only in the pro version.

I only had one active table, so I ended up directly copying that table into an Excel spreadsheet, then copying it back into a WP table block. Then I uninstalled the Supsystic plugin.

I’d note that with the uninstall (deactivating and deleting), the Supsystic tables were emptied but remained in the database – so I did have to manually drop them.

So basically this problem was resolved for me by abandoning use of this particular plugin in favor of an alternate solution.

Please disregard the note about the user being deleted — that turns out to be a different issue. However, the other function problems were real and reported by other users — when I tried to log in the page came up blank. I replicated this several times. I was able to access the dashboard by navigating to the site in a different browser tab, but then when I clicked on links from within the dashboard I also ran into the blank screen issue.
