Warning: in_array() Wrong datatype for second arg menu.php vm3.0.10/ Joomla 2.5

[glesfr]

Hello ,
I'm on Joomla 2.5 and I can't complete the "install this firts" file (com_virtuemart.3.0.10_extract_first) of VirtueMart
Here is the error message :
Warning: in_array() [function.in-array]: Wrong datatype for second argument in /libraries/joomla/database/table/menu.php on line 117
Does anyone can help me up with this problem ?
Thanks in advance for any help

I hope you mean you unzipped com_virtuemart.3.0.10_extract_first.zip and tried installing the two files in there?
com_virtuemart.3.0.10.zip & com_virtuemart.3.0.10_ext_aio.zip

Thanks for your kind reply.
I did unzip the files and try to upload the 1st file (com_virtuemart.3.0.10) then I couldn't complete this very step, with an error as mentionned in my first message.
I'd greatly appreciate any help

Check the file permissions on Joomla's library directory and its sub-directories. Should be 755.

Is your joomla 2.5 up to date?

As this is just a php warning does it really stop the install?

yes it totally stucked the install process.
