Search Results for 'fatal error'

One more update before I leave for the day as we experienced downtime again today. Flywheel was able to tell us the following at the time of the incident:

For the PDF viewer, it looks like that plugin is generating a Fatal Error:

PHP Fatal error: Uncaught TypeError: method_exists(): Argument #1 ($object_or_class) must be of type object|string, null given in /www/wp-content/plugins/wpdm-pdf-viewer/tpls/viewer.php:68

Fatal errors like this will break functionality and can also cause quite a slowdown as code isn’t executing properly. We recommend working with the plugin authors to get that patched up at your earliest convenience.

In addition to the Fatal Error, this plugin is also generating a large number of slow log entries, as is the download-manager plugin. Its possible these two issues are connected. It is generating a huge number more slow log entries than it was yesterday (about 7,000 in the last 24 hours alone).

Things seem to be working better this evening. Not sure if that is related to a lack of site traffic potentially. Still concerned that we were receiving fatal errors in the first place and that there are known vulnerabilities according to Wordfence.

I do see things working currently on that test, but as mentioned previously, it has been very intermittent. Have you been able to confirm the errors sent in my first message? Without any resolution to what was causing that error, I’m very uneasy about knowing this is truly solved.

In our testing, it appears that with the PDF Viewer plugin turned off, downloading files and navigating the site runs more normally and faster. The previews are loading slower than normal and creating all kinds of site speed and preview issues.

We use Wordfence for added security and have found noted vulnerabilities with the Download Manager plugin (https://www.wordfence.com/threat-intel/vulnerabilities/wordpress-plugins/download-manager) which maybe tracks with the fatal errors being called out by Flywheel, our host.

I do appreciate you digging in on this, but we are not comfortable with the answer that there must be a plugin conflict, especially when it appears there are issues happening with Download Manager itself.

I plan to do scheduled “maintenance” at 6 p.m. CST tonight to try to identify any plugin conflicts but I don’t anticipate that revealing much since the errors do seem to be intermittent and worse during business hours when there is traffic on the site.

Hi Nayeem. I’ve got everything on our site up to date, including our theme which was causing some issues as well. I just spoke with our host and they are telling me the following:

I am seeing the same error 600+ times in the logs from the last few days into today and its this –
“PHP message: PHP Fatal error: Uncaught TypeError: method_exists(): Argument #1 ($object_or_class) must be of type object|string, null given in /www/wp-content/plugins/wpdm-pdf-viewer/tpls/viewer.php:68

There is most definitely something going on with this plugin, to be exact, there is 644 fatal errors starting from the 28th into today

Seems like an issue with the plugin itself…can you please assist?

The problem is now resolved by adjusting the code line.
But I guess the issue becomes from something else as the meta_key __wpdm_fileinfo does not exist in the database for this post.
Maybe something went bad while uploading the image ?
Please, add this line code on the next version of the plugin : it won’t fix the main issue but it will prevent from a fatal error.

Hi Nayeem.

I am getting the following error when I try to load the LearnDash courses page:
Fatal error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 15872294 bytes) in /usr/www/users/stagiruuyr/wp-includes/class-wpdb.php on line 3447

I have increased the memory to 1GB and still there is a problem.

There error only disappears and the page loads if I disable the WPDM Reviews Add-On.
I have also disabled all other plugins except for LearnDash, WPDM Pro.

Kind regards
Gayle

Hi, I found a fix, but would be helpfull your opinion about it.

I found the issue to be in src/admin/views/templates/list-templates.php line 46
I was getting a PHP Fatal error: Path cannot be empty, so I commented those lines that had the $tmpdata and now is working. I think the issue is with PHP 8. Was preventing to display all the templates in the admin.

            if(!is_array($template)){
                //$tmpdata = file_get_contents($template);
                $regx = "/WPDM.*Template[\s]*:([^\-\->]+)/";
				//if (preg_match($regx, $tmpdata, $matches)) { 
                if (preg_match($regx, $matches)) {
                    $name = $matches[1];
                } else continue;
            } else {
                $name = $template['name'];
                $ctemplates[] = $ctpl;
            }
