I can't fix my "Warning: preg_match()" error

  • I recently started a new position with a large company that uses WordPress as a content management tool. Some of the projects posted are sensitive, so I cannot give a link to the site.

    I was given a site admin role and the first thing I did was run the plugin updates. I also began to move around some menu items. Shortly after, I received the following error message on the site pages (not home page) as well as some pages on the dashboard.

    “Warning: preg_match() [function.preg-match]: Compilation failed: nothing to repeat at offset 1 in /home/content/01/8942101/html/wp-includes/class-wp.php on line 204”

    I’ve Googled and seen that this has been a problem for many users over the years, but there doesn’t seem to be a universal solution to fix it. I know it is a problem with the permalinks, but I need help fixing it. Any ideas?

    I need to fix this ASAP.

    Thanks!

    I have tried deactivating the plugins, setting the permalinks to default, and then reactivating everything, but it hasn’t helped. (I also checked along the way while I was doing that.. and the warning message disappeared, but so did the project posts – they went to 404 before I reset everything).

    I am not a veteran coder, but I have used WordPress for my own writing for almost 2 years and have never run into this problem… Is there a support line I could call?

    UPDATE:
    After speaking with several colleagues and doing some trial and error, I was able to determine the issue is being caused by Ultimate Taxonomy Manager. However, when I deactivate the plugin, not only does the error message go away, but so does the project content on each page. I’m hesitant to “upgrade” to WordPress Ultimate CMS (as recommended on the plugin settings).

    Has this happened to anyone else? Are there known work-arounds for this or a way to ensure I don’t lose the content if(when) I deactivate/uninstall Ultimate Taxonomy Mgr?

    Thanks!

    I have same error message on Media and Pages only, having just begun building a new site based on imports using HTML Import 2. Deactivating plugin did not work. Have also seen many different explanations over the past 4 years.

    Any further advice appreciated

    Hi Steve

    Unfortunately, I don’t have an answer yet, and XYDAC (the plugin’s developer) hasn’t responded to my inquiries.

    Are you having this problem specifically with Ultimate Taxonomy Manager? Or is the problem with a different plugin? I think my issue is specific to the UTM plugin…

    Well, as I am not a coder, I cannot expplain in detail, but after months of extensive research, consulting WP experts, and having many useless conversations with GoDaddy (our host), we determined the issue had to do with an incompatibility between the most recent WP version and PHP language. I found a coder who was able to go into the file and make the necessary adjustment.
    The message went away, and the site is back up and running. There are still some things that don’t work right (a few permalinks are still broken, etc) but, overall, the site is good now.
