Hiya Martin,
oki doke I've tried it with Google Chrome & IE.
It happens in the WYSIWYG editor, I then need to switch it to the code view & edit out the random font code it put in.
But I've also noticed it does it 90% of times when I modify a post, I will click on Modify, make the changes & then save & it then does the same thing & inserts random font code so the text is tiny, it always sets the font to 2px in size, but sometimes when I hit the "Post" button, it just says page loading then after a while I get a 404. So what I do now (when I remember to) is before I hit "Post" is i will select all my post then copy it to clipboard, then if it fails to post with a 404, then I just start over & paste the info I copied. But sometimes I forget to copy & its annoying having to re-type it all again! lol :(
The preview shows the same as WYSIWYG, so if the font all of sudden went small, then if i hit preview its the same.
Definately a strange one, Is it the default text editor with SMF that your using or have you installed a modded one at all? or made any changes to the code for it maybe ?
Or have you installed any mods at all, it could be if you have then its conflicting with some of the text editor code maybe?
...Well, just as I was typing this, I thought I would do some testing & I think I know what the problem is, Everything is fine until I toggle the views using
then random parts of my post the text goes to 2px. BUT the strange thing is, once Ive edited & removed the font code to bring it back to normal, If i hit the toggle mode again & back, it no longer effects my post, so it seems to only do it the once on the first time I hit toggle view. But that doesn't solve it I know! but at least I know the cause. So imo the problem is the code for toggle view, somewhere in the code when we hit toggle view it's inserting random font code!
But it also does it sometimes when everything looks ok...until I post & then it does it, that...I got no idea! :(
