of xoops 2,4,5

$_MaxCharWidth and $_MaxCharHeight get a high values (2147483651 p ex) only on first call of imageftbbox...

making a big loop on function drawBars(), server slow response and no shows the image...

i resolved adding && ($_MaxCharWidth < 1000000)
working fine now...

Hi people,
I have exactly this same problem. XOOPS is located in a subdirectory of project main.

for identify the user?

if somebody to know some example, will be extremely grateful...

Thanks since already

Hi all from Brazil, im new at here. (my english is not very good)

I have a problem with tableless.
Im not see exit for this.

I have a confusing layout... (click on link)
http://www.leonardo.carvalho.nom.br/arquivos/exemplos/tableless.gif

My idea is
->each square is a one block.

Its possible with "tableless" (no tables tags)?
