Well I have had no luck. I have reflashed the box with Openpli 3.0 and installed all dependencies one at a time and restarted GUI after each one. Installed Ians ondemand and from a suggestion earlier I reinstalled python-lxml_2.2.8-r1_mips32el.ipk and rebooted 9 times.
Still I get Some plugins are not available: Extensions/OnDemand (No module named lxml)
What am I doing wrong?
