Auto Post Thumbnails messed up everything

It shows thumbnails even when i deactivated and deleted the plugin and gives some kind of error in that page.

I am kinda new at this. Someone please help me urgently.

are you using any cache plugins?

Yes I am. But I cleared it. Still no luck ??

Hey, @icekid, Disable all the unnecessary plugins (Remove WP cache plugins).

If the problem is solved, install the plugins one by one till you find the cause.

Thanks!

Ok I guess I found the solution….An empty user meta key is causing the problem.
backup your database and
Run this Sql query…
DELETE FROM wp_usermeta WHERE meta_key = '';

This should fix the problem.

@reuben

I am not sure how to do it. As i said I am new at this.

I tried to search a empty meta_key in phpMyAdmin. But I didn’t find any.

@thejas Kamath

Tired your suggestion. Still No luck ??

if you see this

There is still that stupid thumbnail from that stupid plugin.

Plus in https://www.defenceaviation.com/ for some reason the sidebar doesn’t work. Only one widget doesn’t work it just contains links to blog rolls.

@everyone

I solved it. Turns out the plugin: phpbb_recent_topics was causing problem.

Now only problem remaining is those extra images or thumbnails or whatever.

For example here https://www.defenceaviation.com/2009/04/india-used-airforce-to-attack-its-own-people.html

This was caused by that stupid thumbnail plugin. I removed it. Still no luck.

Did the plugin edit my theme??

I dont think that the plugin has edited your theme. If you can pastebin your theme’s single.php code. It would be easy to find the solution.

I solved it.

The plugin inserted

<?php if ( function_exists("has_post_thumbnail") && has_post_thumbnail() ) { the_post_thumbnail(array(300,225), array("class" => "alignleft post_thumbnail")); } ?>

in theme’s:

single.php
page.php
archive.php
index.php

Removed it and everything is normal. Thank you all for the help. Thanks a lot Reuben

i really want to say that this plugin screwed up my site and i cant get these stupid thumbnails off…thaks for making the dumbest plugin ever
