It looks like it’s a PHP 5.3 issue. The server is still running PHP 5.3 until the hosting company migrates that site to a VPS with a newer OS in the next month. I checked metaslider on my development server, and sites running with versions of PHP higher than 5.3 will remove “default” from that DB field, but it’s not removed if PHP 5.3 is running.
Yeah, at this point it’s just an fyi for you. Re-entering “default” into the DB field and refreshing admin doesn’t clear it out for me. It breaks admin when the word “default” is in that field (or any other word that isn’t “none”), and any new slideshow I create during that time causes the word “default” to be inserted into that field for the new slideshow, which obviously breaks those slideshows in admin as well. Once I clear “default” in tha field for all slideshows, everything goes back to normal in admin, and any new slideshows I create get the “Outline” theme data inserted into that DB field.
Following up, I went into the database using phpMyAdmin, searched the wp_postmeta table for post_id with a value of the slideshow id. That found a meta_key of metaslider_slideshow_theme for that slideshow, which had a meta_value of default. I deleted the word default, saved, then went back to WP admin for MetaSlider and reloaded the page for the slideshow that was causing problems. The widget area showed up again and clicking “Update Slide Image” worked okay. In other words, that slideshow is now working correctly in admin after removing “default” as the meta_value for the meta_key of metaslider_slideshow_theme for that slideshow. So what does that tell us? Hopefully that will give you an idea.
The themes folder is there. Like I mentioned, no errors in console.
Hi, I went through and disabled each plugin but the problem persists. I’m not getting an error in the console. I just noticed I have two old slideshows I don’t use anymore, and they don’t have the problem (widget area shows up for them and update slide image works). So it’s only a problem with my main slideshow that I’ve been using for a few years and for adding a new slideshow. In fact, every time I click Add a New Slideshow it adds “New Slideshow” to the Select Slideshow dropdown but I don’t get the widget area and can’t add a slide (goes to that JSON page).
Not sure if this is relevant at all, but I checked the wp-admin error log and noticed it repeatedly adds the following error:
PHP Fatal error: Cannot use object of type WP_Error as array in /wp-content/plugins/ml-slider/ml-slider.php on line 1334
