I have a problem uploading images in Joomla articles, it gives me the following error: "total size of upload exceeds the limit".

In the php.ini, I have the following variables set:

memory_limit=-1

upload_max_filesize = 256M post_max_size = 256M

And in the Joomla configuration, Media section: Maximum Size=256

It only gives me an error when uploading an image in the 'blog options' section of the articles. In the rest of the sites (for example in contacts) it lets me upload them without problem. Would you know how to solve it?
