UBB.threads PHP Forum Software Community Forums Resources and Customizing How Do I? Max Image file size upload

Humm.
Not sure of your folder hierarchy. Meaning where the forum is located and where you ran the test script.
I would open the ubb cp and near the bottom select php info and look at the local value for
post_max_size
upload_max_filesize
or on the local value column look for anything that has the 2MB value.

The reason I ask is I found one host inmotion that the editable php.ini is not recursive meaning it passes values only to the folder it is in.
If a folder does not have a custom php.ini then it uses the default master file of which you usually do not have access to.
The last few sites I worked on the default file size was 2MB
There are ways around it..
copy the php.ini to multiple folders(not desired)
or place a statement in the htaccess file.

Of course it all could be a moot point if your browser cache has not refreshed since you changed the file size.
