When installing SIGPro one file couldn't be installed

"It was not possible to copy the selected file:
JInstaller::install: Failed to copy file: /tmp/install_4d3ac62d72262/en-GB.plg_content_jw_sigpro.ini to /var/www/vhosts/rvs-tuinbeelden.nl/httpdocs/administrator/language/en-GB/en-GB.plg_content_jw_sigpro.ini "

So I put it manually there and gave it permsission 777

But still something is going wrong:

At the address www.rvs-tuinbeelden.nl/index.php/tuinbeelden/kleinere-beeldjes-van-rvs
I put in  the basic code {gallery}mapname{/gallery} But it shows title and description..

At www.rvs-tuinbeelden.nl/index.php/grafmonumenten I put in the code {gallery}grafmonumenten:180:120:0:2{/gallery} But no title nor description is shown.

Besides that it's impossible to change the permission setting of the label.txt from it's basic value 644. (The permission for stories folder and all the subfolders are all set to 777).

Any idea what could be the matter?

As far as I can see you have solved your issue.

Dear Katia,

I am sorry but no I haven't solved my issue. 

At www.rvs-tuinbeelden.nl/index.php/tuinbeelden/kleinere-beeldjes-van-rvs
I put in  the basic code {gallery}mapname{/gallery} But it also shows title and description which it shouldnot do.

At www.rvs-tuinbeelden.nl/index.php/grafmonumenten I put in the code {gallery}grafmonumenten:180:120:0:2{/gallery} It should show title and description but that doesn't happen.

But most important problem is that I cannot open nor change the label.txt file. (with FTP)

Hope to hear from you soon! Best regards

Check your settings (about title etc) in plugin parameters.
In the seconde link I cannot see the gallery... ???
Did you try to upload a labels.txt folder with your descriptions via the media manager?

Plugin manager - Default caption: read contents of caption files
2nd file I placed gallery back.

Upload labels.txt via media manager gives message: "Possible IE XSS Attack found."
But I managed to delete the old label.txt file with the media manager and uploaded the new labels.txt with ftp

But that is not the proper way
