You should remove the spaces.
Unless, of course, you are quoting a poem, in which case the slash indicates a line break: We review a module theme per user.
Wikipedia has more info : There are usually no spaces either before or after a slash.
Exceptions are in representing the start of a new line when quoting verse, or a new paragraph when quoting prose.
The Chicago Manual of Style (at 6.112) also allows spaces when either of the separated items is a compound that itself includes a space: Our New Zealand / Western Australia trip .
(Compare use of an en dash used to separate such compounds.)
The Canadian Style:
A Guide to Writing and Editing prescribes "
No space before or after an oblique when used between individual words, letters or symbols; one space before and after the oblique when used between longer groups which contain internal spacing", giving the examples "n/a" and "Language and Society / Langue et société".

In print I would leave no space, but for online usage I bracket the "/" with spaces because it is a non-breaking character and results in huge, clunky amalgamations that take up a whole line, leaving the previous line with but a couple of words.
This is the kind of break I mean: If you wanted to use some long words, you could go the antidisestablishmentarianism/pneumonoultramicroscopicsilicovolcanoconiosisroute.
The two long words won't break at a line end because of the slash, but will if the slash is surrounded by spaces.

I believe the correct usage is word/word unless you're writing a line break in a poem: Shall I compare thee to a summer's day? /
Thou art more lovely and more temperate:
/
Rough winds do shake the darling buds of May, /
And summer's lease hath
all too short a date:

Punctuation surrounding a slash is a matter of style.
The Chicago Manual of Style, for example, allows for a space on either side of the slash when either of the separated items has a space itself.
For your example a space on either side of the slash would be appropriate according to that style convention.
Regarding line breaks, you probably want the front space padding the slash to be a non-breaking space, as starting a new line with a slash would be jolting for a reader.

As a technical writer I need to edit content written by engineers.
for some reason they have a tendency to use spaces before and after slashes, and I religiously remove them.
I have started rethinking my inflexibility in this matter as I believe there are times that spaces make the content more user friendly.
A case in point is either/or listings of terms that contain other symbols, for example "PMC_IO51 / XMC_IO_B-9".
The spacing makes it clear that the slash is not part of either term.

Normally, no spaces should be used; however, placing a slash with no spaces between two long, polysyllabic words (common in technical writing) makes the sentence harder to scan.
This could be one case where ignoring your style guide is justified.

I usually put a space before and after / , when indicating alternatives. We review a module / theme per user. Is it correct, or should I rewrite the sentence to remove those spaces? We review a module/theme per user.
Should I write "module/theme" or "module / theme"?

It appears that punctuation surrounding the use of slashes is a matter of style, however, in this example, there should probably be no spaces either side of the slash unless you're writing a poem. Spaces may be more common when separating two long polysyllabic words, something which is common in technical writing. Generally spaces should not be included unless you are quoting from a poem, but the exceptions are technical texts, where spaces can help to avoid confusion, and online texts, where they can help to avoid excessively long amalgamations that take up a whole line.

The spaces should be rmeoved. Normally, no spaces should be used. However, placing a slash with no spaces between two long, polysyllabic words (common in technical writing) makes the sentence harder to scan. Punctuation surrounding a slash is a matter of style. The correct answer to this question will potentially be a question of style. However, it is generally agreed that obliques should have no spaces either side of them unless the two items being separated contain a space themselves.
Spaces should be removed unless you are quoting a poem. Leave no spaces in print but online it is recommended to avoid long and clunky amalgamations. Only have spaces in a poem. It's a matter of style. Spaces can be helpful in technical writing to avoid ambiguities. Spaces can be justified if they make the text easier to read.

It is generally considered that there should be no spaces either side of an oblique. Spaces may be permitted either side of an oblique if the two items in question contain spaces. Punctuation choices when using obliques are a matter of personal style.
